Matl - WG95 - Materials SC - Insulation Testing of AC Electric Machinery with High Direct Voltage
|Working Group Chair||
|IEEE Program Manager|
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.
