6.4A3 MAINTENANCE 6.4.1 TRIP COUNTERS
PATH: ACTUAL VALUES ÖØ A3 MAINTENANCE Ö 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
S1 RELAY SETUP ÖØ INSTALLATION ÖØ RESET TRIP COUNTER DATA setpoint.

played. The relay calculates an estimate of the per-phase wear on the breaker contacts. Arcing current data can be reset to
zero with the
