Modelling and validation of metal oxide surge arrester for very fast transients

High Voltage, 2018
Metal oxide surge arrester models that are currently on rounds suffer from certain deficiencies and as a consequence, they are not in position to portray accurately the arrester residual voltages.

Development of a Low-Energy Mobile Current Waveform Impulse Generator for Application in Low Voltage Surge Arresters [PDF]

Brazilian Archives of Biology and Technology
Surge arresters are at the forefront of protection against voltage surges. The loss of the protective effect of surge arresters imposes accidents and unplanned shutdowns on the power system.

Measurement and Modelling of Leakage Current Behaviour in ZnO Surge Arresters under Various Applied Voltage Amplitudes and Pollution Conditions

, 2018
In zinc oxide (ZnO) surge arresters, leakage current usually flows across the arrester under normal operating condition. Leakage current is one of the factors which contribute towards degradation of surge arresters and therefore, it is very important to ...
