Run the Prefault State for a few seconds and then run the Fault State. Record the BFT time (16.50 cycles). Subtract the Trip time from the BFT time to get the measured Breaker Fail Time Delay (16.50 – 1.49 cycles = 15.01 cycles), which bypasses all the additional time delays included in the Trip tolerance.
