Superseded by 43-2000. Insulation resistance characteristics of rotating-machine windings and the manner in which these characteristics may serve to indicate the condition of the winding are described. The recommended procedure for the measurement of insulation resistance of windings of rotating machines rated 1 hp, 1 kW or greater is presented. The recommended minimum value of insulation resistance of alternating-current and direct-current rotating-machine windings is given. Synchronous machines, induction machines, direct-current machines, and synchronous converters are covered, as well as armature windings and field windings. Fractional-horsepower machines are not included.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
