Partial discharge (PD) taking place in a solid dielectric-bounded cavity involves physical
processes such as free electron supply, discharge development and surface charge …

Residual charges produced in previous partial discharges (PDs) are considered as one
aspect of memory effects that affect subsequent discharge behavior. In this paper, we review …

Understanding a partial discharge mechanism at direct current (DC) is an actual research
topic that requires both modeling, simulations and measurements. This paper describes an …

A simulation model is established to investigate the influence of applied voltage and
temperature on DC partial discharge characteristics of a XLPE sandwich internal cavity …

The presence of various defects including the presence of micro-cavities, cracks, and
contamination of impurities intensifies the field stress inside the insulation when subjected to …

The insulation system represents one of the most critical elements in any high voltage
equipment, inclusive of any cabling and machineries. 60% of the faults and errors occurred …

For a gas‐solid insulation system with direct current (DC) voltage, the surface charge
accumulation and decay phenomenon are directly related to the capacitive‐resistive electric …

In this paper, the discharge frequency was measured for two types of cylindrical cavities at
DC voltage. One was surrounded by polyethylene (PE), while the upper surface of the other …

The power electronic equipment needed in HVDC grids produces an AC ripple voltage with
amplitude of around one-hundredth of the main DC voltage. The high voltage can result in …

Insulation system is one of the most vital elements in high voltage equipment and hence,
investigation on the condition and mechanism of failure of high voltage insulations is …
