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.

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.
