ABSTRACT:
A protection apparatus includes a relay being switchable between a protected state and an operating state, a power consumption sensor, and a controller for permitting a user to switch the relay to the operating state, and for switching the relay to the protected state responsive to sensed power consumption of the electrical equipment indicating nonuse thereof. Accordingly, the apparatus protects the electrical equipment from disturbances carried by the external electrical conductors when the electrical equipment is not in use. The apparatus preferably includes a housing which also serves to mount a plurality of electrical connectors for interfacing between the electrical equipment and the external electrical conductors. In one embodiment, the apparatus also preferably includes a lightning sensor for switching the relay to the protected state responsive to sensing of lightning. Alternately, or in addition, the apparatus may also include a power loss sensor for sensing a loss of power from the power source to the electrical equipment and for switching the relay immediately to the protected state responsive to sensing a loss of power.
