Determination of Gas-Filled Surge Arresters Lifetime

IEEE Transactions on Plasma Science, 2019
In this paper, the functional aging of gas-filled surge arresters (GFSAs) is addressed. Aging is determined by the features of the lifetime. Statistical samples of the random variables of breakdown time and breakdown voltage have been recorded ...

Electrothermal Optimization of Field Grading Systems of Station Class Surge Arresters

IEEE Journal on Multiscale and Multiphysics Computational Techniques, 2019
An electrothermal simulation based procedure for the optimization of the field grading systems of station class surge arresters is presented. The main difficulty consists in the numerical solution of the three-dimensional (3-D) field grading system, and ...

Condition Monitoring of Metal-oxide Surge Arresters using Leakage Current Signal Analysis

IEEE International Conference on High Voltage Engineering and Application, 2018
Online condition assessment of surge arresters is necessary for early detection of problems and subsequent replacement of the device to avoid unplanned downtime and/or damage to the equipment being protected.

Reliability Analysis of Low-Voltage Metal-Oxide Surge Arresters Using Accelerated Failure Time Model

IEEE Transactions on Power Delivery, 2018
Failure progression of metal oxide-based surge arresters in response to exposure to harmonics is modeled using the accelerated failure time model. Multistress accelerated ageing tests, with and without ac distorted voltage stress, are conducted on ...

Surge Arrester Protection and Very Fast Surges

IEEE Power Engineering Review, 1983
The results of this paper suggest that surge arrester protection may not be adequate for very fast rates of rise of lightning currents even considering insulation strength greater than chopped-wave. Additionally, it is shown that prediction of the magnitude and front time of the peak overvoltage is a complex function of lead length, arrester model ...
