A Review of Voltage Distribution on Metal Oxide Surge Arrester and Suggestions for Improvement in High Voltage Applications

IEEE Latin America Transactions
Stray capacitive effect of MOSA may cause non-uniform voltage distribution in both non-conduction and conduction modes. Also, during conduction, there is a delay in operation of arrester, particularly when faced with very fast transient overvoltages ...

A parameter identification technique for metal-oxide surge arrester models

IEEE Transactions on Power Delivery, 2002
Summary form only given, as follows. A simple numerical technique to identify the parameters of metal-oxide arrester models is described. Using measured arrester voltage obtained under impulse test condition, the arrester parameters are determined using an optimization technique. The validity and the accuracy of the model are then assessed by comparing

Effect of Supply Harmonics on Measurement of 3rd Harmonic Resistive Leakage Current of Metal Oxide Surge Arrester

2024 IEEE 3rd International Conference on Electrical Power and Energy Systems (ICEPES)
Metal oxide surge arresters (MOSA) are commonly used for the protection of electrical equipment from surges. Typically, MOSA consists of zinc oxide (ZnO) blocks used to be housed inside ceramic housing.

Potential distribution analysis of suspended-type metal-oxide surge arresters

IEEE Transactions on Power Delivery, 2002
Nonuniformity 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 ...

Advanced Metal Oxide Surge Arrester for Gas Insulated Switchgear (GIS)

IEEE Power Engineering Review, 1984
SF6 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
