Nettet6. jan. 2024 · Four major classes of faults occur in practice in a three-phase transmission network. These are single line to ground fault or SLG fault, line to line fault or double line fault denoted as LL or DL fault, double line to ground fault mentioned as LLG or DLG fault and triple line fault, i.e., LLL or 3L fault. NettetCauses of Ground Faults. As we mentioned, water is a major conductor of electricity and is a particular danger in the case of a ground fault. So, one of the most common causes of ground faults is water leaking in the area or into an electrical box. Additionally, hot wires that are loose or worn could potentially cause a ground fault. dib branch timings
