Protective Measures with Insulation Monitoring

The incremental application of unearthed electrical supply systems (IT systems), requires a careful selection of suitable protective measures, e. g. insulation monitoring devices (IMDs). The combination of IT systems with insulation monitoring is an innovative protective technique, with the great advantages of a more efficient operational safety and reliability, a better fire protection, accident prevention and more. The book gives a detailed description of the unearthed IT system and its application fields, in industry, mining, railway, marine/ oil and in electro vehicles. The various measuring techniques involving insulation monitoring devices are discussed, with an in-depth description of the respective international standards-series, IEC 60364, Low-voltage electrical installations; Part-1, Fundamental principles, assessment of general characteristics, definitions, Part 4-41, Protection for safety – Protection against electric shock; Part 6, Verification and IEC 60479, Effects of current on human beings and livestock – Part 1: General aspects, amongst others.
