Long stretched arcs in motors
Dear Beshires,
I've seen that same effect in several industrial situations, especially when slip rings are involved with lose brushes and DC currents. Overvoltage and Overload conditions (or excessive wear) are generally involved, just as you say.
I think this shows why a quenching process is needed if a stretched arc process is being employed as I propose.
Thanks for the observation.
