The P430C design includes a universal compact case which is equally suitable for both wall or flush mounting owing to reversible connector blocks together with adjustable angle brackets.

The nominal currents or the nominal voltages, respectively, of the measuring inputs can be set with the help of function parameters.

The nominal voltage range of the optical coupler inputs is 24 to 250 V DC without internal switching.

The auxiliary voltage input for the power supply is a wide-range design with a nominal voltage range of 84 to 250 V DC and 100 to 230 V AC. An additional version is available for the lower nominal voltage range of 24 V DC.

All output relays are suitable for both signal and trip duties.

Information Interface Information exchange is done via the local control panel, the PC interface and 2 optional communication interfaces.

One of the communication interfaces conforms to IEC 60870-5-103, IEC 60870-5-101, DNP 3.0 and Modbus and is intended for integration of MiCOM P430C with substation control systems.

The 2nd communication interface (COMM2) conforms to IEC 60870-5-103 and is intended for remote setting access only.

Additionally, the optional InterMiCOM interface (COMM 3) allows a direct transfer of any digital status information between two devices.

Clock synchronization can be achieved using one of the protocols or using the IRIG-B signal input.


Main Functions Main functions are autonomous function groups and can be individually configured or disabled to suit a particular application. Function groups that are not required and have been disabled by the user are masked completely (except for the configuration parameter) and functional support is withdrawn from such groups.

This concept permits an extensive scope of functions and universal application of the device in a single design version, while at the same time providing for a clear and straight-forward setting procedure and adaptation to the protection and control task under consideration.

Distance Protection Fault Detection Logic The distance protection devices are equipped with an elaborate fault detection element that can be adapted to the individual power system. Even when the fault detection conditions are unfavourable it will ensure reliable fault detection as well as selective fault type determination.

For this purpose, the following fault detection measurement elements are implemented in the devices (Figure 4):

> Phase-selective overcurrent detection (I>>)

> Phase-selective undervoltage detection (V<)

> Phase-selective angle-dependent underimpedance detection with adjustable load blinding (Z<)

> Ground fault detection with adjustable neutral-point treatment (using the residual current IN> and/or neutral displacement voltage VNG>).

Undervoltage and underimpedance detection can be enabled separately.

All fault detection measurement elements operate simultaneously.

Inrush Stabilization The operate function of overcurrent detection can be stabilized under inrush conditions if desired. The ratio of the second harmonic component of the phase currents to the fundamental serves as the criterion. This stabilization is either phase-selective or effective across all three phases depending on the chosen setting.

Fuse Failure Monitoring A failure of the measuring voltage caused by a short circuit or line breaks in the secondary circuit can be detected by the internal fuse failure monitoring function. In this event, the distance

protection function will automatically be blocked and if appropriate, the backup overcurrent-time protection function will be activated.

Polygonal tripping characteristic Phase Selection

P430C devices evaluate the distance decision for all fault loops. These loops are selected depending on the fault type determined by the fault detection logic and – where applicable – to the set loop preference, e.g. if only phase-phase-loop should be evaluated in case of phase-phase-ground faults.

To eliminate these problems, the distance protection devices are equipped with a voltage memory with continuous writing of the phase-to-phase voltage VAB into a ring memory as long as the voltage and frequency conditions are satisfied. The directional determination element can access the voltage memory when the measured voltages fall below a set value. Frequency compensation allows the memory to be used as a valid directional reference for up to 2 seconds after fault inception.

Distance and Directional Determination For measured angles within the range –45° to +135°, a ‘forward’ direction decision is issued, for angles outside this range, a ‘backward’ direction decision ensues. The distance decision is obtained by comparing the measured impedance with the set polygonal or circular tripping characteristic (see Figure 3).

Setting: α1 = 40°, σ1 = -20° Settable parameters: Reactance X1 Resistances R1,PP und R1,PG Line impedance angle α1 Four (six) independent distance zones can be set

With P437 the fourth zone can be used as a special zone depending on the set operating mode, e.g. to allow auto-reclosing only on the overhead-line section in cable/line systems or to compensate the bundle conductor effect. The sixth zone is permanently measured and could be used in user-defined scheme logic.


Tripping Timer Stages Each of the distance zones is assigned a settable timer stage. Additional timers serve as directional and non-directional backup timer stages, respectively. Once the backup timer stages have elapsed, the tripping decision proceeds independent of distance measurement.

All timer stages are initialized when a fault is detected. All tripping timer stages can be used separately.

Mutual Compensation When protecting parallel lines, care must be taken for the effect of mutual coupling of the lines in the zero-sequence system. P437 could optionally be equipped with an additional CT input to measure the residual current of the parallel line. This current can be taken into account by the calculation of the ground-fault loop impedances, depending on a settable ratio of the residual currents of the two lines.

Power Swing Blocking Power swings between generators due to severe load variations or system faults may cause measured impedances to enter distance zones. To avoid incorrect tripping, the devices measure the rated change of power over a two cycle window to implement blocking for the duration of the swing.

Alternatively an out-of-step tripping feature can be activated which operates either on fast power change or asynchronous swings.

Measuring Circuit Monitoring The voltage measuring circuits need to be monitored for short-circuits and line breaks. In preference, the auxiliary contact of the voltage transformer m.c.b. is used to block the voltage-dependent protection function in the event of a shorted measuring circuit. Additionally, internal monitoring can be activated so as to check for plausibility of the measured zero-sequence and negative-sequence components of current and voltage. If voltage unbalance is diagnosed then all voltage-dependent protective functions such as distance measurement are blocked automatically.

Furthermore, negative sequence current and voltage are monitored for compliance with set limit values. If the limit value is exceeded for a set period of time then a signal is issued.

Current unbalance monitoring can be used to implement functions such as circuit breaker pole discrepancy.

Backup Overcurrent-Time Protection When a fault occurs in the voltage measuring circuit, distance measurement is no longer possible. In this case, a one-stage backup-over-current-time protection function (BUOC) can be enabled automatically. Activation of the auto-reclosure control function is optional during BUOC operation.

Backup-overcurrent-time protection starting can be blocked by inrush stabilization if desired (see ‘Distance Protection’).

Switch on to Fault Protection Closing of a circuit breaker might inadvertently lead to a short-circuit fault due to a maintenance ground clamp not yet removed, for example.

The function ‘switch on to fault protection’ provides for an undelayed protective tripping during a settable time after a manual close command has been issued. Depending on the operating mode, either a trip command with initialization of the fault detection logic or a zone extension of distance protection according to the set zone extension factors results.

Protective Signaling The distance reach is usually set to values below 100 % line length so as to avoid overlapping of adjacent substations. Protective signaling (teleprotection scheme logic) extends the reach of protection to 100 % by a logic operation on the signals received from the remote substation.

Protective signaling can be operated using one of the standard schemes shown in the table below.

With P437 phase-selective signal transmission is possible.

Where required, the following additional features can be activated:

> Weak infeed trip logic

> Echo

> Transient blocking

> Frequency monitoring (Deblocking).

A test send signal can be triggered via any of the device interfaces.

Protection Interface InterMiCOM (optional)

InterMiCOM allows high performance permissive and blocking type unit protection to be configured, plus transfer of any digital status information between line ends. Intertripping is supported too, with channel health monitoring and cyclic redundancy checks (CRC) on the received data for maximum message security.

InterMiCOM provides eight end-end signal bits, assignable to any function within a MiCOM relay’s programmable logic.

Default failsafe states can be set in case of channel outage.

Phase to Ground Faults

Phase to ground faults have operational impact in protection systems depending on the system neutral treatment.

In low impedance grounded /earthed systems phase to ground faults are followed by short circuit current to be switched off.

In isolated/Petersen Coil grounded systems only information is requested in case of phase to ground faults.

Ground Fault Direction Determination Using Steady-State Values The ground fault direction is determined by evaluating the neutral displacement voltage (e.g. from the open delta winding of the voltage transformer) and the residual current (e.g. from a core-balance or window-type current transformer). The directional characteristic can be set to match the method of system grounding (cos ϕ measurement for Petersen coil, and sin ϕ for insulated neutral). In the cos ϕ circuit, the adjustable sector angle also has an effect so that faulty direction decisions (resulting, for instance, from the phase angle error of the current and voltage transformers) can be suppressed effectively. Operate sensitivity and sector angle can be set separately for the forward and backward direction, respectively.

Alternatively, an evaluation based on current only can be performed. In this case, only the magnitude of the filtered residual current is used as ground fault criterion.

Both procedures operate with either the filtered fundamental or the fifth harmonic component in accordance with the chosen setting.

Ground Fault (Short-Circuit) Protection In the event of single-phase faults with high fault resistance, conventional distance algorithms may not be sufficiently sensitive. This fault condition is covered by the device with a highly sensitive integrated backup protection function, namely a zero-sequence power directional protection function using current and voltage of the zero-sequence network for fault and directional determination. When the set operate values VNG> and IN> are exceeded, detection and selective clearance of single-pole faults can be performed.

Ground Fault (Short-Circuit) Protection Signaling In order to achieve high-speed tripping by the ground fault (short-circuit) protection function, the device is equipped with a supplementary ground fault (short-circuit) protection signaling logic. The operating mode of this logic function is in parallel to and independent of the protective signaling function of distance protection. The only limitations would result if a common transmission channel is used.

The following operating modes are supported:

> Signal comparison release scheme

> Signal comparison blocking scheme

The following functions can be activated as required to suit the individual application:

> Weak infeed trip logic

> Echo

> Transient blocking

> Frequency monitoring

A test send signal can be triggered via any of the device interfaces.


Auto-Reclosing Control The internal auto-reclosing control (ARC) capabilty is 3-pole, trip dependent.

ARC cycles with an high-speed reclosure (HSR) and up to nine subsequent time-delay reclosures (TDR) are possible. HSR and TDR are independently configurable. For special cases, tripping prior to an HSR or TDR can be delayed. Triggering of the ARC function via binary inputs (tripping by a protective device operating in parallel) can be effected.

HSR and TDR reclosures are counted and signaled separately.

Test HSR can be triggered via any of the device interfaces.

Definite-Time Overcurrent Protection A four-stage definite-time overcurrent protection (DTOC) function can be activated in parallel to distance protection. Three separate measuring elements are available for this purpose:

> Maximum phase current

> Negative-sequence current

> Residual current

Starting of the phase and negative sequence current stages can be blocked by inrush stabilization (see ‘Distance Protection’) if desired.

Inverse-Time Overcurrent Protection The single-stage inverse-time overcurrent protection (IDMT) function operates with three separate measuring elements:

> Maximum phase current

> Negative-sequence current

> Residual current

For the individual measuring elements, the user can select from a multitude of tripping characteristics (see Figure 9).

The IDMT protection function can be operated in directional mode. The directional decision can either be accepted from the distance measuring element or can be formed from the negative-sequence current and voltage.

Starting of the phase and negative sequence current stages can be blocked by inrush stabilization if required (see ‘Distance Protection’).

Thermal Overload Protection

Using this function, thermal overload protection for lines, transformers and stator windings of h.v. motors can be realized. The highest of the three phase currents serves to track a first-order thermal replica according to IEC 255-8. The tripping time is determined by the set thermal time constant τ of the protected object and the set tripping level Θtrip

and depends on the accumulated thermal load Θp:

Figure 10 Tripping Time Characteristics of Inverse-Time Overcurrent Protection


Directional Power protection The directional power protection monitors exceeding the active and reactive power limit, a power drop and the reversal of direction at unsymmetrically operated lines. Evaluation of the power is performed using the fundamental of the three phase currents and of the three phase-to-ground voltages.

Over-/Undervoltage Protection The over-/undervoltage-time protection function evaluates the fundamental of the phase voltages and of the neutral displacement voltage as well as the positive-sequence voltage and negative-sequence voltage obtained from the fundamental of the three phase-to-ground voltages. Two definite-time-delay overvoltage stages each are provided for evaluation of the neutral displacement voltage and negative-sequence voltage. Two additional definite-time-delay undervoltage stages each are provided for evaluation of the phase voltages and the positive-sequence voltage.

Evaluation of the phase voltages can be performed using either the phase-to-phase voltages or the phase-to-ground voltages as desired. For evaluating the neutral displacement voltage, the user may choose between the neutral displacement voltage formed internally from the three phase-to-ground voltages and the neutral displacement voltage formed externally (from the open delta winding of the voltage transformer, for example) via the fourth voltage measuring input.

Over-/Underfrequency Protection Over-/underfrequency protection has four stages. Each of these can be operated in one of the following modes:

> Over-/underfrequency monitoring

> Over-/underfrequency monitoring combined with differential frequency gradient monitoring (df/dt) for system decoupling applications

> Over-/underfrequency monitoring combined with medium frequency gradient monitoring

> (∆f/∆t) for load shedding applications

Circuit Breaker Failure Protection With the trip command, a timer stage is started for the monitoring of the circuit breaker action. If the timer elapses due to the persistence of the general starting, a 'circuit breaker failure' signal is issued. This serves to issue a second trip command

(retrip) or, according to the user´s choise, to trip neighbouring protection device (upstream breaker).

The input of a 'circuit breaker failure' signal via an appropriately configured binary input while the general starting persists, effects an undelayed trip command.

Limit Monitoring A multitude of currents, voltages and the measured temperature are monitored to aid operation of the protected line. This function is not intended to be used for protection purposespurposes, as it has an inherent 1 second delay.

E.g. for the 3-phase currents, the phase-to- ground voltages and the phase-to- phase voltages the highest and the lowest value is determined. These are evaluated using an operate value and time delay set by the user. Thereby, these currents and voltages can be monitored for exceeding an upper limit or falling below a lower limit. Programmable Logic User-configurable logic enables the user to set up logic operations on binary signals within a framework of Boolean equations. By means of a straightforward configuration procedure, any of the signals of the protection device can be linked by logic ‘OR’ or ‘AND’ operations with the possibility of additional negation operations.

The output signal of an equation can be fed into a further, higher-order equation as an input signal thus leading to a set of interlinked Boolean equations.

The output signal of each equation is fed to a separate timer stage with two timer elements each and a choice of operating modes. Thus the output signal of each equation can be assigned a freely configurable time characteristic.

The two output signals of each equation can be configured to each available input signal after logic OR linking. The user-configurable logic function is then able to influence the individual functions without external wiring (block, reset, trigger, for example).

Via non-storable continuous signals, monostable trigger signals and bistable stored setting/resetting signals, the Boolean equations can be controlled externally via any of the device’s interfaces.


Global Functions Functions operating globally allow the adaptation of the device’s interfaces to the protected power system, offer support during commissioning and testing and provide continuously updated information on the operation, as well as valuable analysis results following events in the protected system.

Clock Synchronization The devices incorporate an internal clock with a resolution of 1 ms. All events are time-tagged based on this clock, entered in the recording memory appropriate to their significance and signaled via the communication interface. Alternatively two external synchronisation signals can be used according to the selected communication protocol: using one of the protocols ModBus, DNP3, IEC 60870-5-103, IEC 60870-5-101 the device will be synchronized by a time telegram from a higher-level substation control system or in any other case it will be synchronized using the IRIG-B signal input. The internal clock will then be adjusted accordingly and operate with an accuracy of ±10 ms if synchronized via protocol and ±1 ms if synchronized via IRIG-B signal.

Parameter Subset Selection The function parameters for setting the protection functions are, to a large extent, stored in four independent parameter subsets. Switching between these alternative setting groups is readily achieved via any of the device´s interfaces.

Operating Data Recording For the continuous recording of processes in system operation or of events, a non-volatile ring memory entries is provided. The relevant signals, each fully tagged with date and time at signal start and signal end, are entered in chronological sequence. Included are control actions such as the enabling or disabling of functions as well as local control triggering for testing and resetting. The onset and end of events in the network, as far as these represent a deviation from normal operation (overload, ground fault or short-circuit, for example) are recorded.

Overload Data Acquisition Overload situations in the network represent a deviation from normal system operation and can be permitted for a brief period only. The overload protection functions enabled in the protection and control units recognize overload situations in the system and provide for acquisition of overload data such as the magnitude of the overload current, the relative heating during the overload situation and its duration.

Overload Recording While an overload condition persists in the network, the relevant signals, each fully tagged with date and time at signal start and signal end, are entered into a non-volatile memory in chronological sequence. The measured overload data, fully tagged with the date and time of acquisition, are also entered. Up to eight overload situations can be recorded. If more than eight overload situations occur without interim memory clearance then the oldest overload recording is overwritten.

Ground Fault Data Acquisition While a ground fault in a network with isolated neutral or resonant grounding represents a system fault, it is usually nevertheless possible, in the first instance, to continue system operation without restrictions. The ground fault determination functions enabled in the protection device recognize ground faults in the system and provide for the acquisition of the associated ground fault data such as the magnitude of the neutral displacement voltage and the ground fault duration.

Ground Fault Recording While a ground fault condition persists in the power system, the relevant signals, each fully tagged with date and time at signal start and signal end, are entered into a non-volatile memory in chronological sequence. The measured ground fault data, fully tagged with the date and time of acquisition, are also entered. Up to eight ground faults can be recorded. If more than eight ground faults occur without interim memory clearance then the oldest ground fault recording is overwritten.


Fault Data Acquisition A short-circuit within the network is described as a fault. The short-circuit protection functions enabled in the devices recognize short-circuits within the system and trigger acquisition of the associated measured fault data such as the magnitude of the short-circuit current and the fault duration. As acquisition time, either the end of the fault or the start of the trip command can be specified by the user. Triggering via an external signal is also possible. The acquisition of the measured fault data is performed in the measuring loop selected by the protective device and provides impedances and reactances as well as current, voltage and angle values. The fault distance is determined from the measured short-circuit reactance and is read out with reference to the set 100% value of the protected line section. The fault location is output either with each general starting or only with a general starting accompanied by a trip (according to the user's choice).

Fault Recording Fault recording comprises event and disturbance recording along with the stored fault measurands.

While a fault condition persists in the power system, the relevant signals, each fully tagged with date and time at signal start and signal end, are entered into a non-volatile memory in chronological sequence . The measured fault data, fully tagged with the date and time of acquisition, are also entered. Furthermore, the sampled values of all analog input variables such as phase currents and phase-to-ground voltages are recorded during a fault.

Up to eight faults can be recorded. If more than eight faults occur without interim memory clearance then the oldest fault recording is overwritten.

Self-Monitoring Comprehensive self-monitoring procedures within the devices ensure that internal hardware or software errors are detected and do not cause malfunctions of the protective devices. As the auxiliary voltage is turned on, a functional test is carried out. Cyclic self-monitoring tests are run during operation. If test results deviate from the default value then the corresponding signal is entered into the non-volatile monitoring signal memory. The result of the fault diagnosis determines whether a blocking of the protection device will occur or whether a warning only is issued.


Control All data required for operation of the protection and control unit are entered from the integrated local control panel, and the data important for system management are read out there as well. The following tasks can be handled via the local control panel:

> Readout and modification of settings > Readout of cyclically updated measured

operating data and state signals > Readout of operating data logs and of

monitoring signal logs > Readout of event logs (after overload situations,

ground faults or short-circuits in the power system)

> Resetting of the unit and triggering of further control functions designed to support testing and commissioning tasks

The local control panel shown in Figure 1 comprises the local control elements and functions described below.

Operation (1) The integrated local control panel has an LCD

display with 4x20 alphanumeric characters.

17 LED indicators are provided for signal display.

(2) 5 LED indicators are permanently assigned to signals.

(3) The remaining 12 LED indicators are available for free assignment by the user. A separate adhesive label is provided for user-defined labeling of these LED indicators according to the chosen configuration.

Menu Tree (4) By pressing the cursor keys and

guided by the LCD display, the user moves within a plain text menu. All setting parameters and measured variables as well as all local control functions are arranged in this menu which is standardized for all devices of the system. Changes to the settings can be prepared and confirmed by means of the

ENTER key which also serves to trigger local control functions. In the event of erroneous entries, exit from the EDIT MODE with rejection of the entries is possible at any time by means of the CLEAR key C . When the EDIT MODE is not activated, pressing the CLEAR key has the effect of resetting the indications. Pressing the READ key G provides direct access to a preselected point in the menu.

Measured Value Panels The configuration of the local control panel allows the installation of measured value ‘Panels’ on the LCD display. The Panels are automatically displayed for certain operation conditions of the system. Priority increases from normal operation to operation under overload conditions and finally to operation following a short-circuit in the system. The protection device thus provides the measured value data relevant for the prevailing conditions.
