1. Product Introduction

1.1. Introduction

ETR300-S01 is embedded in Distribution Automation 25.8kV SF6 gas insulated load break

switch(Pole mount) control box. It receives measurement information(3 phases current &

voltages) and status information from Switch, and meters current and voltage, detecs FI, Line cut,

Live line/Dead line, Unbalance, and send those information to SCADA(Master station).

As well as, controlling a swich by receiving Control Signal from SCADA, provides Distribution

Automation and minimize a fault area.

ETR300-S01 monitors not only electric quality of dirstirbution line but also, provides Section

operation in case of fault occurring and minimize its fault area.

All events occurring in the distribution line, are saved and provides fault analysis. With using

DNP3.0 Protocol, provides monitored status to SCADA for switch operation. Not only DNP3.0

Protocol, other communication protocols can beprovided by user‟s request.

Switch operation is available by operation buttion on front panel. Fault detect Enable/Diable,

Fault detect Enable/Disable, SECTION function Enable/Disable, operation selection

Local/Remote, Operation lock Lock/Unlock, ALTERNATE SETTING Enable/Disable, SEF

function Enable/Disable, SEC/TIE LOCKOUT Enable/Disable can be set.

INTERFACE SOFTWARE is very much convenient to have the maintenance of Set change and

Operation records in PC. It also has Zoom In/Out feature to analize Fault wave and Digital

operation signal with real time so that it provides much more uniq functions for the users.

Setting Examples

In case of Y-type connection use, set VT2nd[V] for 4V initial value, and if the primary phase-

phase voltage is 15㎸ Ф-Ф, VT ratio is calculated as below.

VoltageФ-Ф = VoltageФ-N × 3

VoltageФ-N = VT 2nd

[V] × VT Ratio

8.66㎸Ф-N = 15㎸ Ф-Ф / 3

8.66㎸Ф-N = 4[V] × 2165

According to the above formula, VT rate is calculated in 2165.

With the same VT2nd[V] and VT ratio, if the primary phase-phase voltage(VoltageФ-Ф) is 11kV,

the primary phase voltage is 6.35㎸Ф-N (=11㎸ Ф-Ф / 3 ), VT secondary input voltage is

3V(=6.35㎸Ф-N /2165)

In case that Δ-type connection is used, if VT2nd[V] is 4V and the primary phase to phase to phase

is 15㎸ Ф-Ф, VT ratio is 3750(15㎸ Ф-Ф /4V = 3750).

ETR 300 has F.I Test in LCD menu to test the fault detect element and normal operation of fault

count. F.I Test function are same as the following.

(1) Basic Operation of F.I Test

Select which phase among A,B,C,N will be produced F.I (plural selection is possible)

After starting FI Test, produces F.I regardless of Pickup Current of Group Setting Menu.

For F.I Test, Sequence is set in the range of 1~3.

F.I Test is Disable when all A,B,C,N phase are OFF or Sequence is 0.

Produce 1000A Fault current for 10 cycle as the setting number. Eacg Sequence interval is 2

second.

After 2 seconds of FI test, temporary fault is generated.

When do the FI test, fault indication lamp of the front panel is lighted and send related

information to the main device without saving as internal event or increasing fault count.

Fault Current Transmission send the faul current to Event according to Fault I Report setting.

At this time, phase that has not done the FI test indicates present load current value.

After the test, fault indication (front panel lamo and BI point) is maintained until FI Reset.

When do the FI test in the status that fault indication is remained, cancel the prior fault

indication and shows “FI information”

(2) FI Setting Value Storage

Selected phase for F.I Test Target and Setting Value for F.I Test Sequence are saved at the started

time of F.I Test.

When F.I test starts, consider as “F.I test mode” the simulated fault current (1000A) permission,

F.I logic performance as much as the sequence setting and LED lighting after F.I set. End the test

mode after finishing these process.

ETR300 has restraint function to prevent the malfunction by inrush current, occurred by switch

closing by reclosing and local and remote after fault occurance. Inrush current restraint function

can be corrected in phase, ground and SEF.

Inrush current restraint function is applied when both Source side and Load side becomes hot

status from dead status or when close the switch. When transient current is over CLPU Pickup

level as Inrush current 1, fault pickup element operates normally instead of inrush current restraint

function. If it is under CLPU Pickup level as Inrushc current 2, restraint during RMT time and

operates the normal fault pickup element. But, if it is under Pickup current as Inrush current 3,

inrush current restraint function is cancelled after Reset time.

7.3. Directional Detection Function

When detect fault, ETR300 distinguish fault current direction and indicates the fault direction in

fault events. Directional Detection setting is composed of Phase, Ground, and SEF elements.

7.3.1. Phase Directional Detection

The direction distinction of phase fault current use normal voltage (V1) and normal current(I1) of

symmetry, and operation are as following.

Distinguish in Forward if I1 pahse about V1 is within ±90° according M.T.A basis and if not

in Reverse.

When fault is occurred in Voltage Metering nearby V1 value can be lost. In this case, use the

ETR300 has changeable PLC for user. PLC has Timer, Counter and Event to control input and

output. Circuit can be optimized to omit unnecessary timer and aux. relay. During ETR300

running, in case the circuit needs to be changed, PLC can be used to meet user‟s need. PLC is

programmed in “ETR300 Interface Software”.
