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 …

Partial discharge (PD) activities are the essential contributor of insulation failure, which
constitute more than 60% for damaging high voltage equipment. This article presents a …

Dielectric polymers are ubiquitous as electrical insulation in electrical power systems and
electronic devices. Electrical treeing is typically regarded as an irreversible degradation …

In this article, electrical tree morphological features in epoxy resin under tensile and
compressive stress are investigated. The applied tensile and compressive stress varies from …

The effect of DC bias on electrical tree growth and partial discharge (PD) characteristics in
epoxy resin (Araldite LY® 5052/Aradur® HY 5052 supplied by Huntsman) is investigated …

Epoxy resins are widely used in equipment such as ultra-high voltage dry-type bushings,
which are subjected to severe electric, thermal, and compressive stresses. Some physical …

This article reports the effect of temperature on tree propagation and phase resolved partial
discharge (PRPD) pattern in epoxy/silica nanocomposite. The results show that tree shapes …

In order to investigate the effect of nano-doping on partial discharge (PD) and electrical tree
growth in cross-linked polyethylene (XLPE), samples of 0.5 wt% magnesium oxide …

Electrical treeing is a leading cause to the eventual breakdown of dielectric polymers under
high voltages. This paper presents a simulation scheme developed based on the phase …

Partial discharge (PD) characteristics are inherently linked to associated electrical tree
growth characteristics. This paper employs both phase-resolved patterns and pulse …
