ABSTRACT:
A simple, inexpensive automatic apparatus for unplugging electrical and electronic equipment from electrical circuits such as power, cable television and telephone circuits when an electrical storm is detected in the vicinity of the device by monitoring conditions that typically change near electric storms and, when one or more indicia of a storm are noted, physically disconnecting the device from the circuit(s) so that substantial insulation is interposed between the device and the circuit(s). In some configurations, re-connection of the electrical or electronic equipment automatically occurs after an electrical storm has passed.
