TRIP COUNTERS
The total number of trips since the
TRIP COUNTERS LAST RESET
date are displayed. Trip counters are used for scheduling
inspections on equipment, for performing qualitative analysis of system problems, and for spotting trends. Any trip condition
will increment the
BREAKER TRIPS
counter and one of the more specific trip counters available. A trip condition is generated
by any feature or input which signals the Trip Relay to operate. If the logic input assigned to the Block Breaker Statistics
function is active, when a trip condition is generated, the trip counters will not be incremented. Trip counter data can be
reset to zero with the
