2. Introduction
2.1. SummaryReclosers are used in distribution system. In case of line fault, due to temporarily
overcurrent, Reclosers can break and make currents several times, thus avoiding longer
network interruptions due to temporary faults. But, in case of permanent fault, because
fault current is still detected after trip and reclosing actions of pre-set sequences, Recloser
is locked out finally as opened.
The pre-set sequences are available to set five times, and for both phase and ground, the
combined operations are possible within the range of 5 instantaneous or 5 times delayed
operating. The first interruption of a fault regarding instantaneous operation, is done
quickly and instantaneously, so that even the fuses in the system do not operate. After
setting time, it recloses back on. And the next interruption has a definite or inverse time
delay. Thus downstream fuses or other protection devices in the network have the chance
to operate and isolate the affected network section, restoring normal operation in the
remaining work. Therefore reclosers make the range of fault section to be limited.
Mainly Reclosers which are installed in overhead distribution line, provide the measurement
of electric current flowing in the distribution line. In case of load current occurrence and
fault detection, it opens and recloses repeatedly according to setting sequence, and at the
sametime, it transmits the status/receives the command to/from HOST and remote controls
of opening/reclosing to minimize the accident. Besides, it stores the whole events in
distribution line, provides the fault causes, and it performs remote monitoring and controls
by transmitting data through DNP3.0, IEC60870-5-101, IEC60870-5-104 protocols.

5.2. Protection Setting Menu
5.2.1 Operation Principle of RecloserThe figure below shows the case of lockout state that, when set with 2F3D of reclosing
sequence, Recloser operates twice of fast operation and 3 times of delay operation against
fault, and then locked out as opened.
- 36 -
<Figure 5-3> Permanent fault for Recloser Sequence
The following figure shows the successful reclosing case that Recloser operates twice of
fast action and inputted. After the lapse of set-Reset Time, Recloser returns, and then
display of LED and LCD are changed from Progress into Ready status. If a fault occurs
again during Reset Time, when the counts of reclosing action reaches to total counts
which shall be calculated from remaining fault counts, the Recloser becomes locked out.
<Figure 5-4> Temporary fault for Recloser Sequence
5.2.2 Operation Principle of FIIf there is a fault on distribution line, protection device(CB, Recloser) does tripping to
protect the system. Then EPIC-R300, Feeder RTU, operates Protection function to detect the
fault, through which it is possible to explore fault section. It is a menu to set and manage
related set value. The basic principle of operation is like a picture below. If there is
permanent or temporary Fault, it detects zero voltage with protective device(CB or

Recloser) after fault current. After detecting zero voltage, EPIC-R300 generates FI. With
protective device’s reclosing success, normal current and voltage are returned. If FI Auto
Reset was set, FI is reset automatically.
If not, push FI reset button on the front or it is reset with transmitted FI reset order in
remote. R300 is designed to generate FI not only for the case that R300 becomes tripped
itself against a fault, but also that other protection devices are tripped.

5) Cold load Operation
If a load has not been powered for a prolonged period, and when the power has again
resumed i.e. by input of circuit breaker, this can impose a higher current than the pickup
value of time-delay overcurrent protection, which could exceed normal settings. These
conditions can exists for an extended period and must not be interpreted as a fault. In
other words, this function is recognized as Cold load circumstance, when no current
measured in the Recloser is maintained for 5 minutes(300sec). If the measured current is
less than the multiples of pick-up, Recloser does not recognize it as a failure. If it is larger
than the multiples of pick-up, Recloser regards the situation as an actual fault, and
performs the same reclosing sequence same as normal operation.

6) Inrush Restraint
When the circuit breaker is putted in order to supply the electricity to a load, Inrush
current is generated in a short time. Inrush restraint is a function to prevent Recloser’s
mis-operation of fault detection elements due to that kind of inrush current at the time of
energization in the line. Inrush restraint can be achieved by two methods ; multiplier can
be applied to pick-up current, and another way is, in case that 1st and 2nd harmonics
contents of generated current is over the constant current, to restrain current for the
setting time.

In single shot operation, Recloser goes directly to lockout after a trip, and will not reclose.
This operation occurs in two cases ; one is the case when Recloser disable in the front,
the controller goes to lockout without reclosing. and another case is that, after Recloser is
put, the fault occurs during the Single Shot setting time, then it goes to trip and
locked-out.
5) Sequence Coordination
When operating with 2 or more Recloser connected in series in distribution line, in order
to prevent the operation of all Reclosers’ being opened at the same time which are
installed both in power supply side and in load side, the Sequence Coordination function
is used to. This function is that, when multiple Reclosers in load side are connected to

one Recloser on the power supply side, only the Recloser experienced a fault is set to
perform the opening operation.
As shown below, if the Recloser in power supply is Active state in Sequence Coordination
mode, in case of line fault, while Recloser in power supply detects the fault current and
operates the opening delayed action, it returns to normal situation by the operation of
Recloser in load side, and then Recloser in power supply will increase the operation
sequence only by one time. Therefore, only sequence of Recloser(power supply side) is in
progress without opening operation, so that even when load Recloser operates to delay
action, Recloser from supply side does not progress the other instantaneous actions in
sequence, but operates to delay action in the same way with load Recloser. If the
reclosing function is restrained, the Sequence Coordination function does not work.
The following rules apply to the Sequence coordination
1) All Reclosers both in supply side and the load must be set at same instantaneous time,
delay characteristics and the same minimum operating Pickup current value. (If the
minimum operating pickup current is wrongly set, the pickup value of power supply must
be larger than the load)
2) All Reclosers must have the same reclosing Time.
3) Recloser in supply should resume 100ms or more of delay time than load Recloser, or
the value of the minimum operating pickup current must be larger than that of load
Recloser.
4) The reset time of power supply Recloser must be set longer than the longest reclosing
time of the load Recloser. This is to prevent Recloser in supply side to be reset mode
during reclosing of load Recloser.

5.2.7 Auxiliary FuncThis function is for monitoring and additional functions of distribution line, key functions
are as follows.
1) Open Line Detect : To set the Phase Loss in distribution line
When phase voltage is maintained below a set value of voltage off for over delay time, it
is determined as Phase Loss. As the phase voltage grows more than setting value, the
Phase Loss is turned off. The percentage of voltage off in Open Line Detect shall be set
equal to or lower than the Live Line Detect voltage level. This is to avoid monitoring the
Open Line when 3 phase voltages are less than Live Line.
2) Sync Check : To check the voltage synchronization of the Source and Load side.
Once the voltages of the Source side and Load side are maintained for the set time,
within the setting range, the Sync Check is “OK”.
- 46 -
If the voltages of Source and Load sides are out of phase setting range, Sync Fail occurs
and then sync LED operates.
3) Live Line Detect : Setting for monitoring live line
Any of the phase from 3 phase voltage from source side is over Voltage On, Hot Line
Source LED light will be on and determines the Source side as Hot Line.
Load side also operates in the same principle.
4) Negative OC : Protection function for reverse phase current.
The setting items and ranges of Auxiliary Function are as follows.
5) Under Voltage : Settings associated with under voltage protection
If you select “3. Use Func” as TRIP, when low-voltage occurs, it trips circuit breaker, and
does not perform any reclosing operation. If you select it as Alarm, it does not trip the
circuit breaker, and record the alarm status in operating information, and it transmits to
the host system over the communication.
6) Over Voltage : Setting associated with over voltage protection
If you select “3. Use Func” as TRIP, when over-voltage occurs, it trips circuit breaker, and
does not perform any reclosing operation. If you select it as Alarm, it does not trip the
circuit breaker, and record the alarm status in operating information, and it transmits to
the host system over the communication.
7) Under Frequency : Settings associated with low-frequency protection
If you select “3. Use Func” as TRIP, when low-frequency occurs, it trips circuit breaker, and
does not perform any reclosing operation. If you select it as Alarm, it does not trip the
circuit breaker, and record the alarm status in operating information, and it transmits to
the host system over the communication.
8) Over Frequency : Settings associated with over-frequency protection
If you select “3. Use Func” as TRIP, when over-frequency occurs, it trips circuit breaker, and
does not perform any reclosing operation.
If you select it as Alarm, it does not trip the circuit breaker, and record the alarm status
in operating information, and it transmits to the host system over the communication.
9) Close Interlock : Settings associated with the function of inhibiting the input depending
on the situation of power system, when Recloser is applied.
For the case of Live Load function with “Enable”, it inhibits the input only when the
voltage is applied to both Source side and Load side. And, in case of Sync Fail function
with “Enable”, it inhibits the input when the synchronization of voltage on the Source side
and Load side is not suitable.
10) Loop Automation : When a fault occurs in a distribution line, protection device
- 47 -
perfoms protecton operation and the load in the lower side of protection devise will
experience a power outage. Thus, the blackout range of the distribution line are spread
to normal condition section as well as fault occurrence section.
For coping with those case, loop control function will operate in the way of separating the
fault section, and supplying power to normal section, then it helps to minimize the outage
time.
EPIC-R300 provides those loop control function which is operable in service only by using
the information about voltage, current, and operating state.
Depending on the configuration of recloser being installed, 3 modes of loop control can
be selected.
- Feeder recloser : the recloser is installed near the substation or inside.
- Midpoint recloser : installation point is between feeder recloser and tie recloser.
- Tie-point recloser : the recloser are usually installed at tie point where two distribution
lines are interconnected.
1) feeder recloser
Protection elements are generally operate when downstream fault occurs in the distribution
line. If it detects voltage loss at power supply, recloser will trip after set time.
In both cases that trip by protection elements and remote operation, loop control function
is automatically stopped.
2) Mid point recloser
Protection elements are generally operate when downstream fault occurs in the distribution
line. If, due to the action at power source side, it detects voltage loss at both sides, it
shall be automatically changed into another setting group after set time.
After downstream recloser or tie point recloser’s operation, the power supply starts to
provide from reverse side. For this moment, the reclosing action shall be hold for a certain
period of time.
3) Tie-point recloser
When voltage loss is detected in the set side, it close after the set time.
After closing, when the fault is detected, it stops and holds reclosing for a sertain period
of time.
The operation by protection elements is possible after normalization of reclosing element.
The activated operation group shall be changed according to feeding direction or setting
- “Dead bus open time”
The loop automation operates when the distribution line is in dead state.
It can be determined by using setting value based on voltage whether distribution line is
dead or not.
The state of loop automation shall be determined as “dead” only when the dead bus state
is maintained for a set time.
The voltage values of all sources and load side shall not exceed the set values.
- 48 -
- “Tie SW open time”
This is the time required to open a “Tie Sw open” in order to repair the distribution lines
to the normal state, if power is supplied from both Tie Sw after the fault is recovered.
- “Tie Sw Source”
It is used to determine the conditions of Tie Sw closing.
BOTH : If any loss for both side, it operates after Tie Sw closing time.
ABC : ABS side is power side, and when RST side is de-energized, then it closes after the
close time.
RST : RST side is power side, when RST side is de-energized, then it closes after the close
time.

1) Feeder recloser trips when the voltage at power supply side is lost.
2) Mid recloser changes to Alt group setting when the voltage of power supply and load
side is dead due to the trip of protection device at power supply, and also changes to
the single shot mode which does not operate reclosing.
3) Tie recloser closes if one side voltage is lost.
4) Feeder recloser closed when the voltage at power supply become live after it is
repaired.
5) Mid recloser closes when the voltage is supplied to both side.
6) Tie recloser opens when the voltage is supplied to both ends.
