Epoxy resin is one of the most common polymers used as part of the insulation system in key
electrical assets such as power transformers and hydrogenerators. Thus, it is necessary to …

The purpose of the present work is to show the validation of a new model to simulate the
physical phenomenon of partial discharge (PD) produced in air voids inside insulating …

In this paper the effects of temperature on partial discharge (PD) activity taking place inside
a spherical void in epoxy resin system are studied. Indeed, some experimental tests …

In this paper a novel approach to model partial discharges (PD) activity taking place inside a
spherical void in epoxy resin system has been traced. The approach is based on a time …

A void in a dielectric insulation material may exist due to imperfection in the insulation
manufacturing or long term stressing. Voids have been identified as one of the common …

In Power Systems, Synchronous Generators (SGs) are mostly used for generating electricity.
Their insulation system, of which epoxy resin is a core component, plays a significant role in …

In this paper, some results are presented on experiments concerning partial discharges (PD)
behavior of epoxy resin samples. The main idea is to see whether a sample with PD at its …

The time evolution of partial discharges (PD) in an artificial cavity in epoxy insulation is
studied using a physical-simulative approach, supported by experimental results. The …

In cases, when there are electrically weak areas in solid dielectric materials (most often
gaseous or liquid inclusions), partial discharges (PD) can be measured when voltage is …

In this paper, some results are presented from experiments concerning partial discharge
(PD) behaviour of epoxy resin samples having 3 wt% nano-and 3 wt% micro-fillers, as well …
