High-voltage power supplies are pivotal in sectors such as agriculture, medicine, and
environmental protection. However, conventional high-voltage sources are associated with …

The paper is aimed at the study of the dynamic of discharges propagating at the surface of
flat PVC insulator (i) with uniform continuous pollution layer and (ii) with uniform …

The surface flashover at atmospheric pressure is the main factor that limits the insulation
performance of high-voltage devices. In order to rise the dielectric strength of the surface, the …

Under rain conditions, the sliding water droplets on the insulator's surface shorten the air
insulation distance between the sheds and even cause a flashover. In order to study the …

This article introduces a complementary criterion for flashover (FOV) of polluted insulators
based on the concept of equivalent impedance variation with discharge length and leakage …

The aim of this paper is the presentation of an analytical model of insulator flashover and its
application for air at atmospheric pressure and pressurized SF6 (Sulfur Hexafluoride). After …

In this paper, the propagation mechanism of creeping discharges up to flashover for short air
gaps is examined and described on various materials based on laboratory de‐noised data …

The acquisition of discharges data is usually affected by external interference leading to
erroneous interpretations. In the viewpoint of improving computation accuracy, the discrete …

This paper presents a dynamic predictive model of creeping discharge until flashover of
solid insulator in air at atmospheric pressure. The model is based on the theory of electrical …

Partial discharge (PD) is one of the main failure contributors in medium voltage (MV) and
high voltage (HV) equipment. Left unattended it can lead to service outages of electrical …
