ABSTRACT:
An apparatus and method are provided for continuously and automatically protecting an electrical device (22) from a potential threat of damaging voltage levels. The apparatus includes a detector (24) for the threat and a protection switching circuit (30) for grounding the electrical device and the detector upon detection. Grounding occurs for a predetermined time interval, after which the detector is again automatically re-activated. Embodiments of detectors include detectors which detect the degree of electrical changes in a surrounding field and detectors comprising a tuned radio receiver. One embodiment includes a device utilization monitor (222) and a detector disable circuit (224) for disabling the detector, and thereby precluding grounding, while a device such as a radio frequency transmitter is being utilized.
