A Novel Approach to Estimate the Quantity of Ingressed Moisture Content Inside Metal Oxide Surge Arrester Using Dielectric Modulus Technique

IEEE transactions on dielectrics and electrical insulation, 2021
In this article, a novel technique is proposed for the estimation of ingressed moisture content inside metal oxide surge arrester (MOSA) in service. For the estimation of ingressed moisture content inside a dielectric precisely, knowledge of frequency ...

Metal Oxide Surge Arrester

IEEE Transactions on Electrical Insulation, 1986
The MOSA (Metal Oxide Surge Arrestor) comprising ZnO non-linear elements has been taking the place of the conventional gapped arresters on a world-wide scale. The ZnO non-linear element was developed in Japan and the application for the surge arrester was also established in Japan for the first time.

Failure Analysis of Metal Oxide Surge Arrester Blocks Based on Repetitive Charge Transfer Rating Verification Test

2022 12th International Conference on Power, Energy and Electrical Engineering (CPEEE), 2022
Surge arresters play a vital role in protecting power system equipment. With its nonlinear characteristics, surge arrester limits the surge voltages in the system to acceptable range and prolongs the life of power system equipment. Surge arrester is made

Pollution Performance Of Metal Oxide Surge arresters

TENCON '91. Region 10 International Conference on EC3-Energy, Computer, Communication and Control Systems, 2005
A metal oxide surge arrester (MOSA) under the effect of conductive pollutants presents two problems namely the insulation performance of the porcelain housing which is more or less similar to insulators working under polluteted condition. Modelling of this type of problem has drawn considerable attention of the researchers and resultq have been ...

Ageing Classification of Metal Oxide Surge Arrester Using Its Power Factor

IEEE International Conference on Properties and Applications of Dielectric Materials, 2021
The third harmonic component of resistive leakage current is considered as the most sensitive ageing indicator of metal oxide surge arrester (MOSA). It is essential to extract the resistive component of the total leakage current prior to determining its ...

Evaluation of Surge Degradation of Metal Oxide Surge Arrester

IEEE Transactions on Power Apparatus and Systems, 1982
The surge degradation of zinc oxide elements under a constant ac stress is investigated experimentally. The results are summed up in a set of formulae and figures from which the degradation of any given condition can be evaluated. The increase ratio of leakage current from the initial value is successfully sed as the indicator of degradation of ...

Simulation of metal oxide surge arresters behavior

2008 IEEE Power Electronics Specialists Conference, 2008
Metal oxide surge arresters are used to protect medium and high voltage systems and equipment against lightning and switching overvoltages. Measurements of the residual voltage of the metal oxide surge arrester indicate dynamic characteristics, and specifically, the residual voltage increases as the current front time descends and the residual voltage ...
