Calculation Method for Differences in Aging Rates of Resistors in Surge Arresters Under Different Impulse Current Waveforms

Abstract: The $\mathbf{8} / \mathbf{2 0} \mu$ s impulse current waveform is commonly used to assess the long-term operational performance of surge arrester resistors. However, the waveforms of impulse ...
