N2 - In this study the watt loss energy measured during varistor conduction at elevated temperature is extrapolated to long-term energy dissipation under standard operating conditions. Artificial degradation tests are conducted on two sets of five varistor samples at the following conditions: 0.85 V1 mA/135°C/96 hours with and without harmonics. Fourier Analysis is applied in order to determine the active powers of all current and voltage components, and hence the watt loss energy at extrapolated time-points. The results obtained indicate higher watt loss dissipated when the voltage is distorted.
