The research and realization of the fault locating detector about distribution network based on waveform and FFT
In the distribution networks, low frequency location method is come up with that the frequency of injected signal is 60Hz and the current is 150mA.In this method, the injected signal is detected by the signal detector along the lines. The detector can indicate the fault orientation through the frequency and waveform showing. By analyzing the frequency of the signals which are detected using FFT, the frequency energies of both the power frequency signals and the injected signals will be obtained. And then the interference about the power frequency signal and others to the detect result can be distinguished. The detector shows the current, frequency and waveform of the detected signals to make the fault point detecting more accurate.
