The waveform shown on Fig. 13-6, appears a lot of clutter on the contact break
point, which is obviously caused by the serious erosion on contact break point. It
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.

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.
