Timing test
Updated 2026-10-27
Data records
- A timing test is a circuit breaker test that records the instant at which each main, resistor and auxiliary contact changes state after a trip or close command, yielding the operating time of each pole and the synchronism between poles and between the contacts of one pole.
- A circuit breaker analyzer performs the timing test by recording the change of state of the main, resistor and auxiliary contacts against time, from which it reports the open and close operations, dwell time and dead time of the breaker.
