Abstract
In the chapter electrical, mechanical, thermal, chemical and other reasons of electric insulation failures are described. Consequences of network insulation failures are discussed. The most frequent problems are misoperation of control and protective devices installed in the circuits. Various cases of misoperation of DC and AC devices caused by insulation faults are presented and explained. Few methods of prevention of devices malfunctioning are given, among others device’s coil shunting by a resistor or a damping filter. Some useful formulas for resistor selection are derived.
