The correlation between partial discharges (PD) and gassing in insulating liquids

10th International Conference on Conduction and Breakdown in Dielectric Liquids, 2002
The authors report on investigations performed to determine the relationship between PD parameters and the dissolved gas generated by partial discharges in mineral-based oil. The PD activity of mineral-based oil is shown to depend upon many parameters, including the influence of the standing time between the filling of the test vessel and the switching

Characterization of Partial Discharges in High-Frequency Transformer Under PWM Pulses

IEEE transactions on power electronics, 2022
Partial discharge (PD) is a phenomenon often occurring in insulation system defects (cavities), which can significantly affect life and reliability. While broad knowledge on PD phenomenology of high-frequency transformers (HFT) has been achieved under ac

Investigation of Partial Discharges in AlN Substrates Under Fast Transient Voltages

IEEE transactions on dielectrics and electrical insulation, 2022
The objective of this article is to characterize partial discharge (PD) inception voltages and patterns at sinusoidal and square voltages in insulating ceramic substrates with generic manufacturing defects. PD tests were conducted on active metal brazed (
