Earthfault
WebSep 10, 2024 · Provision of earth fault protection. One of the most common faults to occur on a motor is a stator winding fault. Whatever the initial form of the fault (phase phase, etc.) or the cause (cyclic overheating, etc.), the presence of the surrounding metallic frame and casing will ensure that it rapidly develops into a fault involving earth. WebEarth fault also occurs when the winding turns come between the neutral and fault point. There are different conditions during the earth fault conditions. In the first case, the current flows into and out of windings. While in the second case, the ampere-turns balance is maintained between windings.
