Maintenance of surge arrester by a portable arrester leakage current detector
IEEE Transactions on Power Delivery, 1988An instrument is described that detects leakage current without disconnecting the arrester ground wire. Better means were developed for detecting deterioration of a surge arrester than the existing appearance inspection, insulation resistance measurement, and leakage current measurement.

A brief history of AC surge arresters
IEEE Power Engineering Review, 1991Since the beginning of AC transmission, approximately 100 years ago, lightning protection of transmission equipment has been provided by gaps and by nonlinear resistors, alone or in various combinations. Protection during the early part of the period (1892-1908) was provided by simple air gaps from line to ground.

Radioactive reliability of gas filled surge arresters
IEEE Transactions on Nuclear Science, 2003The goal of this paper is to determine use of gas filled surge arresters (GFSA) with a built-in radioactive sources in radiative environment. Furthermore, a pseudoempiric method has been developed to determine the GFSA pulse shape characteristics. These results are considered relevant for the use of this component in both military applications and ...

Thermal Stability and Life of the Gapless Surge Arrester
IEEE Transactions on Power Apparatus and Systems, 1981The life of the gapless arrester using the ZnO element is examined experimentally. The mode of degradation due to ac voltage application differs according to the composition of ZnO valve element. The watt loss is not always a linear function with time.

Comments on metal oxide surge arresters surges energy absorption capacity
Conference Record of the 1996 IEEE International Symposium on Electrical Insulation, 2002This paper presents an approach to determine the energy absorption capacity of metal oxide surge arrester resistors. The proposed approach deals with the discharge current peak versus discharge current time relation. A testing method and a statistical evaluation are proposed.

Electrothermal model for complete metal-oxide surge arresters
IEE Proceedings - Generation, Transmission and Distribution, 1999A computational, electrothermal model for a complete metal-oxide surge arrester based on the implicit form of the finite-differences method is presented. The model is used to calculate the cooling curve after the application of overvoltages and the temperature variations during standard test.
