(Specification)Standard Specification for Insulation Resistance Monitor for Shipboard Electrical Motors and Generators
Standard Specification for Insulation Resistance Monitor for Shipboard Electrical Motors and Generators
ABSTRACT
This specification covers monitoring devices (monitors) for the automatic detection and signaling of low insulation resistance values in idle electrical motors or generators, or both. Monitors are intended for permanent installation in both existing or new panels and controller enclosures designed for marine application. These insulation resistance monitors shall be classified in four types: Type I are alternating current generator monitors, Type II are alternating current generator monitors, Type III are direct current motor monitors, and Type IV are direct current generator monitors. The enclosure materials used in the construction of the monitors are to be flame-retardant and the current carrying terminals shall be made of corrosion resistant material. The monitors shall isolate their measuring circuit from the line voltage, while the motor is operating, by the use of an integral isolating relay. In the design of these monitors, environmental factors shall be considered: operating temperature range, sealing, inclination, humidity, and vibration. Also, the monitor relays, voltage characteristics and operating accuracy shall be considered in the design of these monitors. Each monitor shall be subjected to the following: visual and mechanical examination and operational test.
SCOPE
1.1 This specification covers monitoring devices (monitors) for the automatic detection and signaling of low insulation resistance values in idle electrical motors or generators, or both.
1.2 Monitors are intended for permanent installation in both existing or new panels and controller enclosures designed for marine application.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.4 The following safety hazards caveat pertains only to the test method described in 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
