Safety information

Strictly follow the company and international safety regulations.

Working in a high voltage environment requires serious approch to

aviod human injuries and damage to equipment

Do not touch any circuitry during operation. Potentially lethal

voltages and currents are present

Avoid to touching the circuitry when covers are removed. The IED

contains electirc circuits which can be damaged if exposed to static

electricity. Lethal high voltage circuits are also exposed when covers

are removed

Using the isolated test pins when measuring signals in open circuitry.

Potentially lethal voltages and currents are present

Never connect or disconnect wire and/or connector to or from IED

during normal operation. Dangerous voltages and currents are

present. Operation may be interrupted and IED and measuring

circuitry may be damaged

Always connect the IED to protective earth regardless of the

operating conditions. Operating the IED without proper earthing may

damage both IED and measuring circuitry and may cause injuries in

case of an accident.

Do not disconnect the secondary connection of current transformer

without short-circuiting the transformer’s secondary winding.

Operating a current transformer with the secondary winding open will

cause a high voltage that may damage the transformer and may

cause injuries to humans.

Do not remove the screw from a powered IED or from an IED

connected to power circuitry. Potentially lethal voltages and currents

are present

Using the certified conductive bags to transport PCBs (modules).

Handling modules with a conductive wrist strap connected to

protective earth and on an antistatic surface. Electrostatic discharge

may cause damage to the module due to electronic circuits are

sensitive to this phenomenon

Do not connect live wires to the IED, internal circuitry may be

damaged

When replacing modules using a conductive wrist strap connected to

protective earth. Electrostatic discharge may damage the modules

and IED circuitry

When installing and commissioning, take care to avoid electrical

shock if accessing wiring and connection IEDs

mechanism for the day to day operation and even advanced use of the IED.

The keyboard, LCD and LEDs on the front of the IED are what constitute the

HMI. Troubleshooting, monitoring, setting and configuring are all possible via

this interface. Through the screens and menu elements available, as well as

the keypad, the user is able to navigate throughout the menu structure and

move from screen to screen.

The IED is unpacked and visually checked. The connection to the protection

system has to be checked in order to verify that the installation is successful.

The settings for each function must be calculated before the commissioning

task. The functions setting menu have been listed in detail so that the user

can find and change the required settings directly and correctly. For the

different application, the IED can be performed conveniently through

switching the setting group.

For the functions included in the IED can be tested by users, the testing

procedure have been listed as reference to verify that protection function

operate correctly.

After the IED is in service, some checking items also need to be done for

maintenance in order to ensure that the IED is in good condition during

operation, some suggestions have been preset as reference and the user can

perform some other checking items according to the relevant regulations.

RS232 serial port is located on front panel, the software tool in PC can be

connected with the IED via this port to make setting, testing and cofiguration,

etc.

3.2 Connecting to protective earth

Connect the earthing screw on the rear panel to the nearest protective

earthing point in the cubicle. The protective earth cables should be green or

yellow conductors with cross-sectional area 2.5mm2 according to electrical

regulations and electrical standards requirement.

The cubicle must be properly connected to station earthing system, using the

conductor with cross-sectional area of at least 4mm2.

3.3 Connecting the power supply module

The wiring from the cubicle terminal block to the IED terminals must be

connected in accordance with the established guidelines for this type of IED.

The wires from binary inputs and outputs and the auxiliary power supply must

be routed separated from the current transformer cables between the terminal

blocks of the cubicle and the IEDs connections.

3.4 Connecting to CT and VT circuits

CT and VT are connected to the analogue input module on the rear side of

the IED.

Using solid conductor with cross-sectional 2.5-6mm2 (AWG14-10) or stranded

conductor with cross-sectional 2.5-4mm2 (AWG14-12). The screws used for

fixation conductor should be tightened.

3.5 Connecting the binary inputs and outputs

Auxiliary power supply and binary input and output signals are connected

using female connectors. Signal wires are connected to a female connector,

which is then plugged into the corresponding male connector, located at the


29

rear of the IED.

Procedure:

1. Connect signals to the female connector

All wiring to the female connector should be done before it is plugged into

the male part and screwed to the case. The conductors can be of rigid

type (solid, stranded) or of flexible type.

The female connectors accept conductors with a cross section area of

0.2-1.5 mm2 (AWG 24-15). If two conductors are used in the same

terminal, the maximum permissible cross section area is 0.2-0.8 mm2

(AWG 24-18, each conductor corresponding to one cross section area).

If two conductors, each with area 1.5 mm2 (AWG 15) need to be

connected to the same terminal, a ferrule must be used to combine the

two conductors, no soldering is needed. Wires with a smaller gauge can

be inserted directly into the female connector receptacle and the

fastening screw shall be tightened.

2. Plug the connector to the corresponding back-side mounted male

connector

3. Lock the connector by fastening the lock screws

3.6 Making the screen connection

When using screened cables always make sure screens are earthed and

connected according to applicable engineering methods. This may include

checking for appropriate earth points near the IED, for instance, in the cubicle

and/or near the source of measuring. Ensure that earth connections are

made with short conductors of an adequate cross section, at least 6 mm2

(AWG10) for single screen connections.

3.7 RS485 and RS232 ports connection

3.7.1 RS485 port connection

The RS485 interface is capable of half-duplex service with the signals A/A'

and B/B' to transmit signals.


30

The network topology of RS485 adopts bus type of terminal matched, do not

support ring or star network. Use the single and continuous channel as bus.

The terminating resistance is located on beginning and terminal of the bus

cable. The other ports do not need the terminating resistance.

As shown in Figure 9, RS485 port located on the rear side of communication

module. The IED provides two electrical isolation RS485 ports, the two ports

can work at the same time with IEC60870-5-103 protocol supported.

3.7.2 RS232 port connection

One RS232 serial port is provided and located on front panel, which is used to

connect personal computer. The RS232 port adopts half-dupex

communication mode, usually which is connected with 9-pin D-subminiature

female connectors

terminal is pins and the PC termianl is female connector. The terminal of 2, 3,

4 and 5 is connected directly. As shown in the following picture:

Figure 11 Example for serial port connection

The line 4 must be connected directly

3.8 Connecting the GPS

Mount the GPS antenna on the building roof or the place of visibility to all

direction is obtained, top of the antenna should be horizontal. Mount the

antenna to console and fix the console on the building roof with expansion

bolts. The turning radius should not be too small when laying the cables. The

length of antenna cables is designed strictly based on antenna gain, so, it is

not allowed to lengthen, shorten or add connectors that will affect signal

reception or can't receive any signals.


31

The principle for mounting GPS antenna is that the position is visible

completely to all directions in 360°, however, for some special conditions,

mount the antenna at the place with best visibility as far as possible.

The GPS port is located on the rear side of communication module, as shown

in Figure 9, which can be connected with screened twist-pair cable.

Chapter 6 IED testing

About this chapter

This chapter describes the method of hardware testing, such as

power supply, binary input and output, analog quantities and all

functions testing method and testing procedure.


50

1 Introduction

IED test requirements:

Setting value list

The IED setting value must be completed before the testing can start.

Application configuration diagram

Terminal diagram

The terminal diagram and module arrangement diagram, available in the

Technical reference manual, is a general diagram of the IED. but note

that the same diagram is not always applicable to each specific delivery

(especially for the configuration of all the binary inputs and outputs).

Therefore, before testing, check that the available terminal diagram

corresponds to the IED.

Technical application maunal

The Technical application manual contains application and functionality

summaries, function block, logic diagram, input and output signals,

setting parameters and technical data sorted per function.

The three-phase test equipment

The test equipment should be able to provide a three-phase supply of

voltages and currents. The magnitude of voltage and current as well as

the phase angle between voltage and current must be variable. The

voltages and currents from the test equipment must be obtained from the

same source and they must have minimal harmonic content. If the test

equipment cannot indicate the phase angle, a separate phase-angle

measuring instrument is necessary.

Prepare the IED for test before testing a function. Consider the logic diagram

of the tested protection function when perform the test. All included functions

in the IED are tested according to the corresponding test instrunctions in this

chapter.

The response from a test can be viewed in different ways:

Binary output signals


51

Display value in HMI

All setting groups that are used should be tested.

The IED is designed for a maximum continuous current of three

times the rated current

Please observe the measuring accuracy of the IED, the test

equipment and angular accuracy for both of them


52

2 Points for attention during testing

Be familiar with the engineering drawings, engineering and operation

manual and technical application manual

Before testing, check that the short-circuited wire used to avoid CT

secondary circuit opening is connected correctly and firmly. The

short-circuited phenomenon of VT secondary circuit does not exist

It is allowed to plug-in and pull out each module after the power supply

disconnection. Aviod AC current circuit opened when plug in and pull out

the modules

Keep cleaning and pay attention to dust prevention for each module

Adoption the measure of the human body electrostatic grounding

prevention to make sure that the IED is not damaged by hunam

electrostatic

In principle, the electric iron can't be used in field, if the electric iron need

to be used for welding during testing, the welding can be performed after

the power disconnection or using the electric iron with earthed wire

During testing, do not insert the module into the wrong position. When

plug in and pull out the module apply appropriate force instead of

overexerting to avoid pins bending or damage the fastening components

of module

Short-circuited or disconnected terminals temporarily for checking, it

should be recorded one by one and return to original state after the

testing is completed

Using the electronic devices (e.g. oscillograph, etc.) with AC power

supply to measure the circuit parameters, the case of the device should

be earthed in the same grounding with protection IED cabinet

During testing, consider the safety measure between the IED and other

running equipment and the safety measure of related circuit between

external running equipment and the IED

During testing, if the current magnitude that is input into IED is large than

three times of rated current, it should be noticed that the time should not

be too long


53

When energizing the IED in the first time, using multimeter to check the

power supply, the circuit of voltages and currents are connected correcly

to avoid short circuit or open circuit

Tighten all the screws of all terminals again for the new project in order to

prevent improper connection, and plug in and pull out all the modules

again to aovid the modules loosing result from operation or installation


54

3 Preparing for test

3.1 Introduction

Please read the corresponding manuals that is provided by manufacturer

in detail before testing, try best to understand the basic operation,

protection principle and the relevant capabilities. If have any questions in

this procedure, please inquire the field service engineer or the technical

support engineer of SiFang.

All checking should be done before energizing, inspection well and no

damage on the surface, all modules are inserted firmly, the insulation of

the power circuit are satisfied the specified requirement.

Disconnect the external circuit before testing to avoid safety accident or

injuries to the human

If the modules are needed to be plugged in or pulled out, make sure that

the power is disconnected, and the measure of prevention electrostatic

should be done in order to avoid the damage to module or performance

degradation

The opened or short-circuited terminal temporarily should be recorded in

detail in order to return to original state reliably

3.2 Connecting test equipment to IED

Before testing, connect the test equipment according to the IED specific

connection diagram. Pay special attention to the correct connection of the

input and output current terminals. Check that the input and output logical

signals in the logic diagram for the function under test are connected to the

corresponding binary inputs and outputs of the IED. The testing connection

diagram is shown in Figure 12.

The user must verify that the connections are correct and the analog signals

are measured correctly after connection completed.

Procedure:

1. Inject a symmetrical three-phase current and voltage at rated value

2. Inject a phase-to-phase voltage and phase-to-phase current at rated

value

3. Check that the magnitude and phasor of analog quantities displayed in

LHMI are in accordance with the input values

4. Inject an asymmetrical three-phase current and voltage at rated value in

two phases

5. Check that the magnitude and phasor of analog quantities displayed in

LHMI are in accordance with the input values

6. If the compared value is consistent, perform the testing, if the compared

value is different, check the analog circuit connections

4 Testing the power supply

4.1 Checking the self-startup performance

Power on the IED, in order to check the self-startup performance of the IED,

energizing the IED with the voltage rised slowly from zero to 80% rated

voltage, at this time, observe the green “Run” LED on the front panel that

should be lighted continuously. After the DC power disappears, the normal

closed contact should be disconnected, which can be tested using the

multimeter, the contact is show in Figure 10.

4.2 DC power on and power off testing

Changing the DC power to 80% rated voltage, power off and power on the

power supply some times, the “Run” LED on the front panel should turn off

and turn on correspondingly. The normal closed contact should be in the “on”

or “off” state. The contact is show in Figure 10.

4.3 Checking the expiry date of power supply

When period checking, check the expiry date of the power supply module, if

the power supply module has been used more than 5 years, please replace it.

5 Checking the analog channel

5.1 Checking and adjusting the zero drift

MainMenu/Testing/Zero

In this menu, the zero drift values of all analog channels have been listed in

detail, check that the zero drift is met the requirement. Generally, the

requirement of the current channels is <0.01In, the voltage channels is <0.5V.

If the zero drift value is not satisfied the requirement, adjust the corresponding

zero drift.

MainMenu/DevSetup/Zero

MainMenu/DevSetup/Save

It is allowed to check zero drift after energizing the IED for 5 minutes, when

adjusting the zero drift, disconnect electrical connection of the IED, test

equipment, standard source and external circuit, make sure that there are no

any inputs to analog terminals, select the menu and adjust zero drift. After

zero drift adjustment succeed, enter into the " Save " menu to complete the

adjustment.

5.2 Checking and calibrating

MainMenu/OpConfig/Analog

MainMenu/OpConfig/Metering

The analog quantities scale for protection function is not used to be adjusted,

the accuracy is guaranteed by hardware. For the scale adjustment, Only the

measurement channel is adjusted.

Before testing, disable all of the connectors and binary settings in order to

avoid the protection function startup or maloperation.

Using the test equipment with 0.1 grade, connect the voltages and currents of

test equipment to the corresponding input terminals to check the magnitude

and phase angle of voltage and current. The magnitude tolerance of IED

displaying value and external injected value should be less than ±2.5%

(phase voltage vaule tolerance <0.2V when voltage channel is 1V, zero


58

sequence voltage tolerance <0.2V when voltage channel is 3V; current value

tolerance <0.02In when current channel is 0.08 In).

MainMenu/DevSetup/Scale

MainMenu/DevSetup/Save

Make sure that zero adjustment have been completed before scale

adjustment, and then inject rated voltage and current, after the standard

source output steadily, enter into the menu described above to adjust scale.

After scale adjustment succeed, enter into the " Save " menu to complete the

adjustment. And then check the measurement value, the accuracy

requirement is: tolerance of voltage and current should be less than ±0.2%

and tolerance of power should be less than ±0.5%.

Note: during testing, if the measuring tolerance of the analog quantities are

large than the required range, check that the testing connection, testing

method and external measurement meter is correct, the testing source has

not wave distortion, before all of the exteral equipments are checked, it

should not adjust or change the components of the IED immediately.

6 Testing binary input

MainMenu/Testing/BI

Check the binary input status in this menu, all the binary input status should

be displayed as "empty circle" icon. Make sure that the circuit of binary input

is in good condition, the power of binary input have been connected (24V,

110V or 220V). Test the binary input one by one according to the engineering

drawing, the tested binary input status displayed in HMI should be displayed

as "solid circle" icon.

9 Checking before operation

Note: The following items are only for reference. Users should make the

proper operation guideline based on the actual site conditions

9.1 Checking the LED

Power on the IED, the LED “Run” is lit steadily in green, other LEDs should be

extinguished.

9.2 Checking the display on LCD

In normal operation condition, the information of “year-month-day, hour :

minute : second, magnitude and angle of analog quantities, measurement

value, the function connectors status and the current setting group” should be

scrolling displayed on the LCD.

9.3 Checking the clock

After setting the date and time of the IED, power on and off the IED with five

times in short time, checking the tolerance of date and time is within the

permissible range.

9.4 Checking the voltage and current

Inject system currents (load current must be larger than 0.08In) and voltages

into the IED, and then check whether the magnitude, phase angle, polarity

and phase sequence of each measuring analog value are correct or not.

9.5 Checking the setting group

Make sure the active setting group is correct.

9.6 Checking the setting

Checking the settings one by one of each group which are possibly used in

the actual operation modes.


177

9.7 Checking the binary input

Check the state of all binary inputs. Particularly ensure that the IED is not in

test mode, meaning that the green “Run” LED is not flash continuously

9.8 Checking the normal operation mode

9.8.1 Trip and close test with the circuit breaker

9.8.1.1 Switching the circuit breaker state by local command

Trip and close the circuit breaker, the corresponding feedback state of circuit

breaker injected via binary inputs should be read out and compared with the

actual state of circuit breaker, the displayed state should be in accordance

with the actual state.

9.8.1.2 Switching the circuit breaker state from remote control center

If the IED is connected to a remote substation via SCADA, the corresponding

switching tests may also be checked from the substation.

9.9 Put into operation

If all the checking items described above and the other checking items need to be

Chapter 7 Operating maintenance

About this chapter

This chapter introduces attentions and the required checking,

operation after updating software or replacing modules and the

measure for alarm information.


180

1 Attentions during operating

Warning

Do not disconnect the secondary circuit connection of current

transformer without short-circuiting the transformer's secondary

winding. Operating a current transformer with the secondary

winding open will cause a masssive potential that may damage the

current transformer and may cause injuries to humans.

Caution

Never connect or disconnect a wire and/or a connector to or from a

IED during normal operation. Dangerous voltages and currents are

present that may be lethal. Operation may be disrupted and IED and

measuring circuitry may be damaged.

Note

Strictly follow the power system operation maintenance instruction

or regulations, the following items for reference:

During operating, prohibition the following operation manually:

Touch the parts of IED with electricity

Plug in and pull out each module

Manually operation to the HMI menu:

Testing binary output

Changing setting value

Set setting value

Set systme parameter

Change the IP address

Fault occurrence during operation, if the protection IED tripping, the


181

corresponding LED in front panel will be lighted, and the event reports

will be displayed in HMI; if the autoreclosure function operate, the

corresponding LED will be lighted and the reports will be displayed in

HMI

If the alarming class I appearance during operation, stop running the IED,

record the alarm information and inform the responsible engineer, at this

time, it is not allowed to press the Reset button. If the alarming class II

appearance, record the alarm information and inform the responsible

engineer to analyse and deal with.


182

2 Routine checking

Checking the LEDs status

Checking scroll display information in HMI

Checking the setting group number


183

3 Periodical checking

Check that the inside and outside of the IED are cleanly and no ash

deposition

All components (including the chips, transformer and relay, etc.) of the

IED are fixed well, no loosing phenomenon, the IED apperance is regular

and no damage and distortion phenomenon

The buttons are operated flexibly with good feeling and fixed reliably

All the IED terminals for connection are firmd without loosing

phenomenon, and the marked number are clear and correct

Energizing the IED with DC power supply for several seconds, the green

“Run” LED and protection function LED that connector have been

enabled will be lighted without any alarm or operation lED lighted (if

lighted, press Reset button to reset), the analog quantities is displayed in

HMI

Check the zero drift and scale

Check the operation setting values

Measure the output voltage of power supply

Check the alarm circuit

Check the binary input

Check the tripping and closing circuit

Test the insulation resistance

Chapter 8 Transportation and storage

About this chapter

This chapter describes how to transport and store the IED.


190

1 Transportion

The IED can be transported by means of conveyance, such as car, train, ship, etc. In order to ensure the perfect performance of the IED, prevent the IED from rain, snow, vibration, shock and bump.


191

2 Storage

If the IED is to be stored before installation, this is must be done in the original

transport casing in a dry and dust free place. The packed IED should be

stored in a waterproof and snow proof place without acid or alkaline or other

corrosive gas and explosive gas. The storage temperature is from -25°C to

+40°C, and the relative humidity does not exceed 80%. Observe the

environmental requirements stated in the technical data.
