Abstract

A power test unit for automatic monitoring of electrical systems comprises a gradual power circuit that is manually controlled to increase the input line voltage slowly during test. A current sensor circuit continuously monitors the current being drawn by the electrically operated apparatus, while voltage sensor circuits continuously monitor the internal voltages of the apparatus. Also, a ground current sensor circuit continuously monitors the ground circuitry of the product. If errors occur, a power-down circuit automatically cuts off power to the apparatus, terminating the power-up procedure to avoid damage. The cause of the error is sensed by an error indicator circuit, and a visual indication of the source of error may be provided by a display panel having a multiplicity of lamps connected to the different circuits.
