An electrothermal model for complete metal oxide surge arresters
11th International Symposium on High-Voltage Engineering (ISH 99), 1999A computational, electrothermal model for a complete metal-oxide surge arrester based on the implicit form of the finite-differences method has been presented. The model has been used to calculate the cooling curve and the axial temperature profiles following the application of overvoltages The computed results have been checked against measurements.

Advanced Metal Oxide Surge Arrester for Gas Insulated Switchgear (GIS)
IEEE Power Engineering Review, 1984SF6 gas has outstanding dielectric strength and heat transfer property. This suggests that zinc oxide (ZnO) elements whose value of E in E-J characteristic is higher than the value of the elements used in a porcelain type arrester is suitable to metal enclosed metal oxide surge arresters (MOA) for gas insulated switchgears (GIS). Several kinds of newly

Return voltage measurements on metal oxide surge arresters
11th International Symposium on High-Voltage Engineering (ISH 99), 1999A number of diagnostics are currently available to monitor the condition of metal oxide surge arresters. Very often a number of these diagnostics do not provide meaningful interpretation about the condition of arresters. The authors have experienced one such anomaly during their involvement with multipulse operating duty tests on distribution type ...

Potential distribution analysis of suspended-type metal-oxide surge arresters
IEEE Transactions on Power Delivery, 2002Nonuniformity of potential distribution of metal-oxide (ZnO) surge arresters reduces service lifetime of the arresters. The metal-oxide surge arresters of polymer housings developed can be suspended in different places. A combined method of electrical field and electric circuit is proposed to analyze the potential distribution of the suspended ...

The Response of Metal Oxide Surge Arresters to Steep Fronted Current Impulses
IEEE Transactions on Power Delivery, 1986Measurements of the residual voltages of metal oxide surge arresters have been made using a variety of impulse current waveshapes. The behaviour of both metal oxide and conventional SiC non-linear resistors has been observed and compared. The appearance of “voltage spikes” at short times, ca 0.15 us, on the fronts of residual voltage records has been ...

Pressure Relief Design and Performance of Metal Oxide Surge Arresters
IEEE Transactions on Power Delivery, 1986Surge arresters with porcelain housing must not have explosive breakage of the housing to minimize damage to other equipment when subjected to internal high short circuit currents. Also, arrester porcelain housings are generally susceptible to undesirable thermal shock.

Comparison of different metal oxide surge arrester models
International journal of emerging sciences, 2011Two methods for modeling metal oxide surge arresters are presented and compared: the IEEE Working Group 3.4.11 surge arrester model and the simplified surge arrester model proposed by Pinceti and Giannettoni. The comparison of model performances and accuracy is conducted in the program package EMTP – RV.

Application of Metal-Oxide-Varistor Surge Arresters on Distribution Systems
IEEE Power Engineering Review, 1982The emergence of the metal-oxide varistor (MOV) has made a significant impact on station-class surge arrester technology. Areas in which MOV arresters will provide superior protection on distribution systems are examined even though the current discharge voltage characteristics of MOV arresters are the same as those of conventional surge arresters ...
