Comparison of partial discharge (PD) calibrators from 0.1 pC to 10 nC

Metrologia
Main text High-voltage partial discharge (PD) tests require calibration of PD measurement systems using PD calibrators which provide known values of the apparent charge. A set of travelling reference calibrators was circulated among 14 participating laboratories and each laboratory reported apparent change and rise time measured using ...

Detecting and Monitoring Insulation Failure: A Review of Partial Discharge (PD) Detection Techniques

International Journal of Advances in Engineering and Management
The reliability and efficiency of electrical systems vitally depend on electrical insulation to prevent electricity leakage during transmission. However, due to various operational and environmental factors such as humidity, thermal stress, and others, insulation materials degrade over time. Therefore, detecting and monitoring insulation degradation at
