IEEE Trial-Use Recommended Practice for Pulse-Type Partial Discharge Measurements on Individual Stator Coils and Bars (Approved Draft)
Published By | Publication Date | Number of Pages |
IEEE | 2023 | 49 |
New IEEE Standard – Active. Pulse-type partial discharge test methods for individual form-wound stator coils and bars that are equipped with PD suppression coatings and energized with a sinusoidal voltage source are described in this recommended practice. A uniform procedure for measurements in terms of apparent charge at frequencies below 1 MHz and for measurements in millivolts at higher frequencies, up to 300 MHz is also provided in this recommended practice. This document does not provide pass/fail criteria, but it does describe the measurement circuit, the simulated slot, external factors affecting the measurements, the recommended method for calibration or normalization, appropriate test voltage levels, the need for and parameters of conditioning, and it provides guidelines for interpretation of test results.
