In this standard are set forth methods for the measurement of test voltages and wave shapes used in dielectric tests of electrical apparatus or insulating material. These tests are in three classes: 1. Puncture tests. 2. Flashover tests. 3. Voltage proof tests. The tests may involve the use of alternating current, direct current, or surges from surge generators. Different pieces of apparatus may require different dielectric tests, some requiring power frequency or direct current tests only; other apparatus may require surge tests in addition. The specific requirements for any particular type of apparatus will be found in the standard dealing with that type of apparatus. This standard deals with the measurements themselves

Working Group Details
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No Superseded Standards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No Inactive-Withdrawn Standards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
