Metal Oxide Surge Arrester: A Tool for Lightning Stroke Analysis
2021 IEEE International IOT, Electronics and Mechatronics Conference (IEMTRONICS), 2021Surge arrester is used to protect the equipment of electrical transmission and distribution systems from the effects of lightning and switching overvoltage. They are very much reliable devices which can work for decades without causing any problems provided they are properly designed, configured, and maintained.

A Wide-Range Model for Metal-Oxide Surge Arrester
IEEE Transactions on Power Delivery, 2018This paper presents an electric model of a metal-oxide surge arrester (MOSA). The proposed electric model accurately represents the MOSA in a wide range of frequencies and amplitudes. The model was developed and validated based on MOSA electrical behavior in each one of the three operating regions of the zinc-oxide (ZnO) surge arresters, and in a ...

Analysis of Thermal Effects for Polymer-Housed Metal-Oxide Surge Arrester Under Multiple Strokes
IEEE Transactions on Power Delivery, 2022Multiple strokes are the main factors affecting the safe and stable operation of power equipment. As the core lightning protection equipment, arresters are also frequently thermally collapsed due to multiple strokes.
