Abstract:
The procedure for quality control testing of external discharges on stator coils, bars, and windings of large air-cooled ac electric machines is described in this recommended practice.
Scope:
This recommended practice provides procedures to detect external discharges in form-wound bars and coils and complete stator windings of rotating machines operating in air with a rated line-to-line voltage greater than 2300 V at power frequency. The recommended practice is applicable to bars, coils, and complete stator windings. The recommended practice covers two inspection methods--the visual blackout test and the use of corona imaging instruments.
Purpose:
The purpose of this recommended practice is to suggest specimen preparation, test parameters, and procedures for detecting external discharges associated with bars, coils, and complete stator windings using the above-mentioned methods. It also recommends acceptance criteria and a procedure for retest in the event of a test failure.
