Abstract
A method of testing a voltage protection device in a circuit is provided. The circuit comprises a source and load and a detector is provided in parallel with the protection device. The method comprises opening a switching device provided in the circuit. The method further comprises detecting a property of a voltage spike caused by the rate of change of current in the circuit inductance produced by the opening of the switching device to determine the condition of the protection device.
