Scheme communication logic for residual overcurrent
protection ECPSCH

M13926-2 v6

Prepare the IED for verification of settings outlined in Section

"Preparing the IED to verify settings"

Before testing the communication logic for residual overcurrent protection function ECPSCH, the four
step residual overcurrent protection function EF4PTOC has to be tested according to the
corresponding instruction. Once this is done, continue with the instructions below.

If the current reversal and weak-end infeed logic for earth-fault protection is included, proceed with
the testing according to the corresponding instruction after testing the communication logic for
residual overcurrent protection. The current reversal and weak-end-infeed functions shall be tested
together with the permissive scheme.

Testing the directional comparison logic function

M13926-7 v2

Blocking scheme

M13926-9 v6

1.

Inject the polarizing voltage 3U0 at 5% of

UBase

(EF4PTOC) where the current is lagging the

voltage by 65°.

2.

Inject current (65° lagging the voltage) in one phase at about 110% of the set operating current,
and switch the current off with the switch.

3.

Switch the fault current on and measure the operating time of the communication logic.
Use the TRIP signal from the configured binary output to stop the timer.

4.

Compare the measured time with the set value

tCoord

.

5.

Activate the CR binary input.

6.

Check that the CRL output is activated when the CR input is activated.

7.

Switch the fault current on (110% of the set operating current) and wait longer than the set
value

tCoord

.

No TRIP signal should appear.

8.

Switch the fault current off.
