IEEE Recommended Practice for Insulation Testing of Large AC Rotating Machinery with High Voltage at Very Low Frequency

Terms that have a specific meaning in VLF testing are defined, and VLF test equipment and wave shape are described. A uniform procedure for testing the armature insulation of large AC machines with VLF voltage is provided. Constants for relating VLF tests to power-frequency and direct-voltage tests to obtain equally effective test levels are recommended.
