Response to Norm Dill's message...Years back I spent a week at the
Biddle School in Plymouth Meeting, PA, supposedly learning how to detect
partial discharges (arcs that do not bridge conductive electrodes) in
insulators. Partial discharge (sometimes called, erroneously, "corona")
is what is responsible for long term destruction of insulation, in many
cases. Most resistant materials are inorganics, less resistant are
natural organics (paper), and least resistant are synthetic
organics (epoxy encapsulants, for example).
