Abstract
A simple numerical technique to identify the parameters of metal-oxide arrester models is described. Using measured arrester voltage obtained under impulse test conditions the arrester parameters are determined using an optimization technique. The validity and the accuracy of the model are then assessed by comparing the predicted against the measured values of arrester energy, initial slope, residual voltage, and the overall deviation. Application of the arrester model on network system studies is illustrated.
