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.

3) SEF Rec Count

4) Single Shot Operation

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




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




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.
