Anotation

This specification covers the requirements and testing procedures for five types of electrical insulation monitoring devices intended as permanently installed units that are used in the detection of ohmic insulation faults to ground in active AC ungrounded electrical systems. This specification does not address devices which are not intended for DC or AC ungrounded systems that operated with DC components, unless AC to DC conversion is isolated from the monitored system with transformers. Information required in the equipment manual that shall be provided with this system are also detailed.
