Study on Performance Evaluation of TEV Partial Discharge Detector

[摘要] Transient Earth Voltage (TEV) detection technology has become one of the important detection methods for high voltage electrical equipment. However, due to the lack of uniform standards within the industry, the equipment manufactured by the manufacturers is not of good quality, resulting in the performance evaluation problems of the TEV partial discharge instrument during the purchase and acceptance process. Therefore, this paper proposes a signal simulation evaluation method, and analyzes in detail the advanced function evaluation of TEV partial discharge instrument including frequency characteristics, signal linearity, sensitivity, pulse count, and discharge source positioning performance. it is possible to have a more complete understanding of the performance of the TEV partial discharge meter.
