OPERAND DESCRIPTION
Trip all three breaker poles
A single-pole trip-and-reclose operation is initiated
Trip breaker pole A, initiate phase A breaker fail and reclose
Trip breaker pole B, initiate phase B breaker fail and reclose
Trip breaker pole C, initiate phase C breaker fail and reclose
Initiate a three-pole reclose
Three-pole trip must be initiated
Any trip is initiated by the trip output
Phase distance zone 2 timer is initiated by the trip output
Ground distance zone 2 timer is initiated by the trip output
Asserted when the trip bus 1 element picks up.
Asserted when the trip bus 1 element operates.
Same set of operands as shown for TRIP BUS 1
Underfrequency 1 has picked up
Underfrequency 1 has operated
Underfrequency 1 has dropped out
Same set of operands as shown for UNDERFREQ 1 above
Wattmetric directional element 1 has picked up
Wattmetric directional element 1 has operated
Same set of operands as per WATTMETRIC 1 above
Logic = 0. Does nothing and may be used as a delimiter in an equation list;
used as 'Disable' by other features.
Logic = 1. Can be used as a test setting.
