Insulation design and evaluation via partial discharge (PD) test for power electronics application
2017 IEEE Electric Ship Technologies Symposium (ESTS), 2017Insulation design is important for medium voltage level, high power density power electronic equipment. This is especially true in order to achieve a high reliability and long lifetime, in conjunction with a reasonable insulation size and weight that is important for electric ship applications.

Partial discharge (PD) detection on medium voltage switchgears using non-invasive sensing methods
2012 IEEE International Conference on Condition Monitoring and Diagnosis, 2012Like in any high voltage asset, knowledge about the presence of partial discharge in the insulation system can provide vital information about the health condition of HV apparatuses. For switchgears, a traditional PD measurement according to IEC 60270 requires the disconnection of power cables from the switchgear, and the setup of a test circuit at the

Initiation and formation of partial discharges (PD) in mineral based insulating oil
Proceedings of 1993 IEEE 11th International Conference on Conduction and Breakdown in Dielectric Liquids (ICDL '93), 1994This paper reports the results of fundamental investigations concerning the behavior of partial discharges (PD) in mineral-based oil with the aim of characterizing the physical mechanisms that lead to the initiation and formation of PD pulses. First the influence of the parameters temperature, moisture, pressure and oil condition on the PD inception ...

European Transactions on Electrical Power, 1996
AbstractIn this paper some possibilities of further applications of a known “Streamer Partial‐Discharge Model” are proposed. These possibilities refer to the relation between the observed partial‐discharge (PD) magnitude and the applied field to the insulation.

Improvement of partial discharge (PD) resistance of epoxy resin by using sulfur‐containing additives
Electrical Engineering in Japan, 1994AbstractIn the field of high‐voltage engineering, it has been desired for a long time to improve the internal PD resistance of epoxy resin without lowering other properties. Recently, the authors discovered that some sulfur compound as curing agents or simple additives improved the PD resistance of rubber markedly, and here an attempt has been made to ...

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