Abstract :
The detection of small current ground fault line is one of important problem in power system. This paper presents a novel method to give the correct decision when the fault happened. This method only use of the energy variation, unlike other method use of the waveform, phase, and amplitude in particular time domain, or harmonics in special frequency domain. This method is advantageous to use neural network to give the correct decision. The validity of fault line detection principle and method are verified by the theory and experiment data
