Abstract
A ground fault detection system for locating a ground fault in a direct current (DC) power transfer system is provided. The system includes a ground fault detection component and a current sensor. The ground fault detection component includes a first switch and a first resistive element electrically coupled to each other in a series configuration. The ground fault detection component also includes a second switch and a second resistive element electrically coupled to each other in a series configuration. Furthermore, the current sensor is operatively coupled to a load and is configured to measure a fault current at the load upon switching at least one of the first switch or the second switch to a conducting state.
