Abstract
The recommended methods for standard testing of high-voltage varistors demand application of high voltages and intensive currents that is inconvenient and needs extensive power consumption. These methods require metallization of the prepared ZnO structures that increases costs of testing. Another method of varistor quality and endurance evaluation by the third harmonic index measurement at relatively low voltage range has been analysed. The results of the THI measurements for the selected HV varistor types has been presented in the paper. The applied measurement system is also described and usefulness of the proposed method for varistor testing at their fabrication stage has been considered.
