摘要:
Certain embodiments of the invention may include systems and methods for determining electrical ground faults. According to an example embodiment of the invention, a method is provided determining ground leakage electrical faults. The method includes providing a voltage source having a positive lead in communication with a first contact conductor and a negative lead in communication with a second field conductor, wherein the first contact conductor is connected to a ground through a first resistor Rp, and wherein the second field conductor is connected to the ground through a second resistor Rn; monitoring a first voltage potential associated with the first contact conductor; and determining a condition associated with the first contact conductor, based at least in part on the monitored first voltage potential.
