can be verified via burnishing the contact or changing the circuit breaker.

For the primary voltage waveform shown on Fig. 13-7, the damped attenuation
cycles obviously reduced on the spark period, the amplitude became lower,
which is evidently caused by capacitor leakage.
Fig. 13-7
The waveform on Fig. 13-8 shows the accidental pumping during contact closing
period. The irregular beating is caused by insufficient spring force.
Fig. 13-8
The curve on Fig. 13-9 shows the contact angle is too small during the
magnetizing period, which is caused by too large contact gap.
