Abstract

An apparatus includes a plurality of surge protection devices (e.g., multiple metal oxide varistors connected in parallel) configured to be coupled to a power system, a plurality of mechanical actuators associated with respective ones of the surge protection devices and configured to indicate status of the associated surge protection devices, and a detector circuit configured to sense actuation of the actuators and responsively determine a protection status of the plurality of surge protection devices. The detector circuit may include a plurality of switches configured to be actuated by respective ones of the actuators. The detector circuit may further include a processor coupled to the plurality of switches and configured to determine states of switches and to determine the protection status based on the determined status of the switches. The processor may be configured to interpret the status of the switches based on a stored identifier.
