Abstract:

A ground fault detection and shutoff system for underwater power transmission provides protection to divers from swimming into electric fields. This system uses DC power to monitor the true resistance of the load system rather than the AC power to the load. The system comprises DC power supply, ground fault monitor, circuit breaker and isolation transformer which monitors the systems DC resistance to ground and shuts off the power system if the resistance falls below a preset value.
