Optimisation of zinc oxide surge arrester design using gravitational search algorithm and imperialist competitive algorithm [PDF]

, 2019
Reducing electric field stress near the energised end of surge arresters is very important because it may increase the lifetime of the highly stressed ZnO column in vicinity of the high voltage electrode.

Model Arrester SiC Menggunakan Model Arrester ZnO IEEE WG 3.4.11 [PDF]

, 2005
Arrester model is needed to analyse the insulation coordination in power system. The model should give a suitable respon for varying transient fault. In this paper, we conduct simulation that modified from IEEE WG 3.4.11 model.

A novel embedded voltage‐clamped circuit for multilevel modular converters submodule to suppress very fast transient overvoltage

High Voltage
The submodule in multilevel modular converters experiences a very fast transient overvoltage (VFTO) during switch operation of gas‐insulated switchgear, which also results in overvoltage on power devices, such as thyristors and insulated gate bipolar ...

Prediction of ZnO Surge Arrester Degradation Based on Temperature and Leakage Current Properties [PDF]

, 2018
Temperature and leakage current on the ZnO arrester are interrelated with each other. In low conduction region, voltage-current characteristics of ZnO surge arrester are highly dependent on temperature.

Mathematical Modeling of Passive Techniques Designed for PT Ferroresonance Suppression

International Journal of Electrical Power & Energy Systems
Ferroresonance often inflicts severe damage on electrical equipment like potential transformers (PTs), surge arresters, and circuit breakers. In this paper, a new passive (P) technique using Cex (external parallel capacitor) is proposed and its ...
