6.5.3 Protection
Scheme
In the following protection scheme tests, a dynamic test set with a three-phase voltage source and
current source is required to simulate power system pre-fault, fault and post-fault conditions.
In the following command tripping test, the remote end is not simulated and the receiving signal is
simulated by energizing a binary input circuit locally. If an end-to-end synchronized test is
possible, then it should be conducted.
The autoreclose function can be tested together with these tests. A permanent fault should be
applied to test a reclose-onto-fault.
Zone 1 tripping
This performs instantaneous or time-delayed, and single-phase or three-phase tripping depending
on the fault types, setting of trip mode control switch [Z1CNT] and autoreclose mode switch
[ARC-M].
Zone 1 tripping should be checked for the fault at 50% of the zone 1 reach setting.
Operating time is measured on operation of the trip output relay. It will typically be 1 cycle in case
of instantaneous tripping.
Check that the indications and recordings are correct.
Zone 2 tripping
Check that three-phase time-delayed final tripping is performed for all kinds of faults. Faults
should be set midway between zone 1 and zone 2.
Check that the operating time is 1-1.5 cycle plus zone 2 timer setting.
Check that the indications and recordings are correct.
Zone F tripping
Check that three-phase time-delayed final tripping is performed for all kinds of faults. Faults
should be set midway between zone 2 and zone F.
Check that the operating time is 1-1.5 cycle plus zone F timer setting.
Check that the indications and recordings are correct.
Zone 3 tripping
Check that three-phase time-delayed final tripping is performed for all kinds of faults. Faults
should be set midway between zone 2 and zone 3.
Check that the operating time is 1-1.5 cycle plus zone 3 timer setting.
Check that the indications and recordings are correct.
Zone R1 tripping
Set the scheme switches [ZR1BT] and [ZR2BT] to "On". (The [ZR1BT] and [ZR2BT] default
setting is "Off".)
Check that three-phase time-delayed final tripping is performed for all kinds of faults. Faults
should be set in the center of zone R1.
Check that the operating time is 1-1.5 cycle plus zone R1 timer setting.
Check that the indications and recordings are correct.
