Webb11 juli 2016 · A ground fault is an unwanted electrical connection between a line and the ground. It can be caused by insulation breakdown, bad weather, or physical stress. You can protect against faults using protective devices, including CTs, PTs, relays, circuit breakers, and fuses. Your protective devices must be coordinated for the best … Webbground fault current. This ground return impedance is usually difficult to calculate. If the ground return path is relatively short (i.e. close to the center tap of the transformer), the ground fault current will approach the three phase short-circuit current. Theoretically, a bolted line-to-ground fault may be higher than a three-phase
