12.1.1. Trigger Source
y
Occurred Protection element pickup
y
Occurred Fault trip command active
Depending on pickup size, if interval between pickup and trip is within 15 cycles including
prefault cycles(4 cycles), then record pickup cycles. But if the interval between pickup and trip
are not within 15 cycles, then record pickup cycles and trip cycles. These operations are very
useful to examine.
