Test of delayed fault clearing for single pole tripping
• Connect the test set for the injection of three phase voltages and currents to the appropriate
terminals of the IED.
• Enable the delayed fault clearance for single pole tripping by setting
(Enabled) , Del3PhOp to FALSE (Disabled) and also connect the inputs BLKDLFLT and
FUSEFAIL to FALSE.
• Also assume circuit breaker is in closed position, that is input CBCLD is high, prior to fault
occurrence.
• Create a single phase fault on phase A such that phase A voltage is lower than
quadrature phase to phase voltage and set
current such that it exceeds set
• Check that output TRIN is activated after a set delay of
• Check that TRIP and TR_A are generated with the conditions described after a set delay time
t1Ph and the outputs ARST and ARST_A are also activated.
of
• Check that activated trip signals and pickup signals are blocked by enabling BLKTR and
BLKST.
• Check that all activated signals are disabled by BLOCK input.
• If required, perform creating faults on the remaining phases in the similar way.
Test of delayed fault clearing for three pole tripping
• Connect the test set for the injection of three phase voltages and currents to the appropriate
terminals of the IED.
• Enable the delayed fault clearance for three pole tripping by setting
(Enabled) , Del1PhOp to 3Ph (Disabled) and also set the inputs BLKDLFLT and FUSEFAIL to
FALSE.
• Also assume circuit breaker is in closed position, that is, the input CBCLOSED is high prior to
fault occurrence.
• Create a BC fault such that their phase voltage magnitudes are lower than
corresponding quadrature phase to phase voltage and set
• Check that TRIP, TR_A, TR_B and TR_C are generated after the set delay time of
ARST, ARST3PH, ARST_A, ARST_B and ARST_C are also activated.
• Check that activated trip signals and pickup signals are blocked by enabling BLKTR and
BLKST.
• Check that all activated signals are disabled by BLOCK input.
