New standards for insulation monitoring devices (IMD)

 

Reliability of supply is a central task in electrical energy supply. In the event of a fault, the main tasks of the protection and monitoring equipment include the protection of humans and animals, the avoidance of unexpected interruptions in operation, as well as early information about impending hazards. A particularly important aspect is the selection of power supply system and the related protection and monitoring devices. In unearthed power supplies (IT systems), insulation monitoring devices have a crucial role. The characteristics of these products have now been revised and re-written in a new edition of the European product standards EN 61557-8, -9 and -15. With this latest edition the increased requirements from practice and also new metrological capabilities are addressed.
