1. Scope | ||||||
1.1 This specification covers two (2) types of electrical system insulation monitoring devices. 1.1.1 Type I is an ac device intended as a permanently installed unit for use in the detection of ohmic insulation faults to ground in active ac ungrounded electrical systems up to 1000 VAC, having dc components up to 1500 VDC. 1.1.2 Type II is a dc device intended as a permanently installed unit for use in the detection of ohmic insulation faults to ground in dc ungrounded electrical systems up to 1500 VDC. 1.2 Limitations - This specification does not cover devices that are intended for operation in ac ungrounded systems without dc components. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. The following precautionary caveat pertains only to the test methods portion, Section 7 of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
