Artificial Intelligence Tracing of Inherence Leakage Current between Power Line and Earth

The paper proposes an artificial intelligence method to trace inherence leakage current between power line and Earth, which can be used in history records of only one residual current (RC) detection point. Firstly, it gives the common topology structure of residual current detection in Low voltage power line and defines three ingredients in TLCE (Total Leakage Current to Earth): ILCE (Inherence Leakage Current to Earth), TLCES (Total Leakage Current to Earth after Sub-switch) and BLCE (Burst Leakage Current to Earth). Then the paper analyzes the features of those three ingredients of leakage current. Finally, it gives out an artificial intelligence method to trace inherence leakage current which can be used in leakage current alarm threshold adjustment of electric fire prevention system.
