Soveltamisala

This specification covers insulation monitoring devices for stripboard electrical systems. Materials covered by this specification include Type I (ac device) and Type II (dc device) electrical system insulation monitoring devices used in the detection of ohmic insulation faults to ground in either active ac ungrounded electrical systems with dc components (Type I) or dc ungrounded electrical systems (Type II). However, devices used in ac ungrounded systems without dc components are not included. The devices shall undergo conformance and routine tests to ensure that the device meets the requirements specified. Conformance tests shall included testing of response time, peak voltage, input impedance or resistance, built-in meters, and impulse voltage withstand capabilities, whereas routine tests shall include testing of response value, self-test function, built-in meters, and voltage.
