Abstract
An electrical grid system including a phase conductor, a neutral conductor, and a neutral-to-ground conductor configured to conduct current flow between the neutral conductor and a ground. The electrical grid system further includes a fault detection sensor including a current sensor configured to sense current flowing along the neutral-to-ground conductor. The fault detection sensor further includes a controller having an electronic processor that is configured to receive signals indicative of the current flowing through the neutral-to-ground conductor from the current sensor, monitor the received signals for an occurrence of an event associated with the current flowing along the neutral-to-ground conductor; and output an occurrence of a fault in the electrical grid system based on detecting occurrence of the event.
