Abstract
Disclosed are systems and methods to determine a direction to a fault of an electrical generator using sensitive current. A ground fault is determined using voltage signals from the generator installation. Incremental residual values of the sensitive current, along with the voltage, are used to determine a direction to the fault. The generator may be high-impedance grounded. The systems and methods further indicate the direction to a fault where multiple generators are connected using a common generation bus.
