Abstract
A ground fault protection system includes a power switch including a source-side and a load-side. The power switch is structured to receive a load current from a power source at the source-side and selectively output the load current from the load-side to a load. A first voltage measuring device is structured to measure a first voltage of the source-side while the power switch is not conducting the load current. A second voltage measuring device is structured to measure a second voltage of the load-side while the power switch is not conducting the load current. A controller is structured to determine a source-side-to-ground voltage based on the first voltage, determine a load-side-to-ground voltage based on the second voltage, determine a ground fault is occurring, and determine a direction of the ground fault relative to the power switch.
