The partial discharge (PD) event in high-voltage insulation releases energy, exerts mechanical pressure, and generates elastic waves. Detecting and locating these PD events through short-duration acoustic pulses is well established, particularly in g

Impulsive underwater discharges have been investigated for many decades, yet the complex pre-breakdown processes that underpin their development are not fully understood. Higher pre-breakdown energy losses may lead to significant reduction in the mag

This paper informs on the flashover strength of three materials: Delrin (polyoxymethylene), HDPE (high-density polyethylene) and Ultem (polyetherimide) with smooth surface finishes, in zero-grade air at -0.5, 0 and 0.5 bar gauge, and at 90% relative

New, more stringent environmental requirements for electrical insulation liquids have led to the development of novel, more environment‐friendly liquid dielectrics. Ester fluids, introduced several decades ago, provide a viable alternative to tradi

Gas-filled plasma closing switches (PCSs) are essential components of high energy density pulsed power systems used to generate short, high-power (tens MW to several GW) impulses. In practical applications, PCSs are required to operate in high-curren

In pulsed power engineering, solid spacers are used to insulate high voltage parts from extraneous metal parts. The applied voltage at which a discharge process initiates is important in the design process. In this paper, a method to potentially incr

Understanding of the influence of experimental conditions on the breakdown voltage of composite insulation is important to facilitate optimal design of high voltage systems. This includes ensuring that the statistical analysis performed on breakdown
