This recommended practice provides uniform methods for testing insulation with high direct voltage, specifically form-wound windings of ac electric machines typically rated 2300 V or higher. Recommendations for both (a) routine maintenance or repair testing of a machine that has been in service and (b) acceptance testing of new equipment in the factory or in the field after installation where DC testing is selected are defined.

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No Superseded Standards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No Inactive-Withdrawn Standards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.
IEEE Recommended Practice for Insulation Testing of AC Electric Machinery (2300 V and Above) With High Direct Voltage
This recommended practice provides information on the use of high direct voltage for proof tests and for periodic diagnostic tests on the ground wall insulation of stator (armature) windings in ac electric machines.
