Organization: IEEE
Publication Date: 21 March 2002
Status: active
Page Count: 57
scope:

This recommended practice provides uniform methods for testing insulation with high direct voltage. It applies to stator (armature) windings of ac electric machines rated 2300 V or higher. It covers acceptance testing of new equipment in the factory or in the field after installation, and routine maintenance testing of machines that have been in service.

Purpose

The purpose of this recommended practice is to:

a) Provide uniform procedures for performing high direct-voltage acceptance tests and routine maintenance tests on the main ground insulation of windings of ac electric machines.

b) Provide guidance in analyzing the variations in measured current versus applied voltage so that the condition of the insulation can be more effectively assessed.

c) Compare direct-voltage testing with alternating voltage testing.
