Embodiments test MOV arresters. One embodiment comprises applying a plurality of voltages to a high voltage lead of the MOV arrester, the plurality of voltages being changed between an initial test voltage and final test voltage (corresponding to a point of conduction of a reference MOV arrester); determining a resistive current through the MOV arrester for each of the voltages; determining information corresponding to the resistive current when the applied test voltage corresponds to the point of conduction of the reference MOV arrester; comparing the determined information with information associated with the point of conduction of the reference MOV arrester; determining that the MOV arrester has passed the test when the determined information corresponds to the information associated with the reference MOV arrester; and determining that the MOV arrester has failed the test when the determined information does not correspond to the information associated with the reference MOV arrester.
