How does the grounding method of a distribution transformer affect the magnitude of ground fault currents?

The grounding method of a distribution transformer directly influences the magnitude of ground fault currents. Different grounding methods provide different paths and impedances for the fault current to flow, thereby affecting its magnitude. Solidly grounded systems have a direct, low-impedance connection between the transformer neutral and ground. This results in high ground fault currents, which allow protective devices to quickly detect and clear the fault. However, these high currents can also cause significant damage to equipment. Resistance grounded systems insert a ....
