“…The flashover voltage under the influence of dry band was discussed in references [36], [62], [70], [71], [74], [112], [132]. The flashover voltage of glass insulators under dry bands with five scenarios of pollution distribution were tested in [36]. The results showed that dry bands had a significant effect on the flashover voltage, in which the flashover voltage increased with a decrease in the dry band area [36].…”

Over the past decades, extensive experimental-based research works have been carried out to investigate the flashover phenomenon on the performance of polluted transmission line insulators. The critical focus has been on developing methods that can determine the safety, reliability, and sustainability of the overall power transmission network based on experimental results obtained from polluted insulators' flashover voltage tests. In this paper, a systematic review of available scientific works, published as early as the 1990s, for the analysis of pollution flashover voltage, is undertaken. The review mainly focuses on factors influencing the efficiency of transmission line insulators under polluted conditions. Specifically, publication databases utilizing various synonyms and keywords associated with the terms "contaminated insulators" and "flashover voltage test" have been scrutinized. The search has resulted in 1364 articles, from which 97 articles have satisfied the review requirements and have been subsequently analyzed to determine the parameters associated with polluted insulators. Major factors that affect the performance of insulators, including electrical and environmental impacts, are discussed. Variations in factors affecting flashover test development and insulator efficiency are also considered. Overall, the current analysis provides an important insight toward successful evaluations of the health of transmission line insulators and research advancements of electric power transmission line insulators.INDEX TERMS Flashover voltage test, polluted insulators, high voltage insulators, transmission line.

“…Numerical techniques are also employed to analyze insulators surrounding electric fields. It can be achieved by employing computational methods such as the finite element method [ 17 , 18 ], boundary element method [ 19 ], and charge simulation method [ 20 ]. These computation techniques are cost-effective, efficient, and accurate compared to laboratory testing, which requires a sophisticated environment and a complicated testing process.…”

Field-Dependent Pollution Model under Polluted Environments for Outdoor Polymeric Insulators

et al. 2022

In-depth understanding of the pollution problems such as dry bands and the polymeric aging process requires better determination of electric field strength and its distribution over the polymeric surface. To determine the electric field distribution over the insulator surface, this research proposes utilizing a novel approach model based on nonlinear electrical characteristics derived from experimental results for polluted polymer insulators. A case study was carried out for a typical 11 kV polymeric insulator to underline the merits of this new modeling approach. The developments of the proposed pollution model and the subsequent computational works are described in detail. The study is divided into two main stages; laboratory measurements and computer simulations. In the first stage, layer conductance tests were carried out to develop nonlinear field-dependent conductivity for the pollution modeling. In the second part, equipotential and electric field distributions along the leakage were computed using the finite element method (FEM). Comparative field studies showed that the simulation using the proposed dynamic pollution model results in more detailed and realistic field profiles around insulators. This may be useful to predict the formation of dry bands and the initiation of electrical discharges on the polymeric surface.
