Protective Measures with Insulation Monitoring

With the increasing use of unearthed power supply systems (IT systems), the selection of suitable monitoring equipment is a question of great importance. The combination of an unearthed power supply system (IT system) and insulation monitoring opens the road to a special protective technique. The advantages of this technique are increased operational reliability, increased fire protection and better accident prevention. The book describes this type of system and its application areas in locations for medical use, in ships, in industry and mining. The various techniques used in the German Federal Republic are compared to those in the United States. The historical development of the protective conductor system and its application are also described. The various measuring techniques used by this insulation monitoring devices are discussed, and the pertinent regulations are quoted.
