Abstract
An apparatus for isolating electrical loads during a power supply transfer interruption event, including an electrical circuit interposed between an electrical power source and a load which has a voltage detector for continuously detecting voltage supplied to the load from the power source, comparing the detected voltage against a predetermined desired voltage and outputting a signal indicative of an out-of-limits voltage condition from the power source to the load, an interrupt switch for receiving the output from the voltage detector and interrupting the supply of power to the load during an interval of no more than 1 cycle of the power supply, and a reset switch for restoring the power supply to the load.
