Abstract:
A ground stabilization network including a circuit with an EMI filter circuit to filter out ground referenced interference and internal fault current detection circuitry with an integrated trip circuit to stop the flow of power in case of a fault condition, which might result in a safety hazard. The EMI filter circuit includes a resistor and a reactive portion, both connected in parallel between neutral or return line and ground, mounted between the trip circuit and a current sensor. The current sensor senses differences between the current in the hot or positive line and the current in the neutral/negative or return line, and causes the trip circuit to trip if a predetermined difference in current is sensed.
