There's a ton of stuff if you google "switching transients". There are pictures of blown up utility transformers.
When the circuit opens there is energy stored all over the system in equipment and devices that were powered, motors, transformers, capacitor filters. The switching transients, closing and opening, are a powerful noise in a short period of time. Any noisy signal can be resolved as a sum of sinewaves, and an arcing transient can contain every frequency well into rf and above. An event log would capture high frequency sinewaves, probably with components that are too fast for the recorder as the stored energy in each connected equipment releases that energy into the remaining system.
