Open/Close time measurements on
circuit breakers


We are able to measure the operating time on circuit breakers, from MV to HV plants, showing the time of opening and closing time, and the time discrepancy between the poles.

Usually in addition at this test, also the pole micro-resistance is performed by injecting 100 A dc.
