Oscillographic analysis of short circuit test of circuit breaker

This is a very professional question, and there is little information about it on the Internet.

Generally speaking, there will be:

Network side voltage of each phase

Each phase current

Recovery voltage of each contact (inter-electrode voltage of contact)

switching signal

According to the above waveform data, we can calculate:

Such as flow time, expected current, power factor, first-phase open circuit, arcing time, cutoff value, maximum recovery voltage, reburning or reburning.
