Insulation Monitors Settings Selection

  • Piotr Olszowiec
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 167)


In the chapter general requirements set to insulation monitors selection in AC and DC networks are given. Examples of regulations requirements for circuits insulation equivalent resistance are presented. Traditional method of setting isometers response values is described. Modified approach for settings selection of DC and AC networks isometers takes into account assessment of electric shock and fire hazards as well as devices misoperation risk. Novel criteria for setting isometers are developed. Insulation monitors application for devices misoperation risk detection is discussed. Few examples of dedicated systems for these hazards detection are given.
