Abstract
The authors are developing the technology of total distribution automation for performing load control, line switch control and automatic meter-reading by using ripple control (outbound signal in medium voltage), current answer-back signal (inbound signal in medium voltage) and phase pulse signal (two-way communication signal in low voltage distribution line). The authors cover the waveform-detecting method which has been developed as the sending and receiving technology by phase pulse signal. They also show that, by application of the waveform detecting method, more than 99.9% of total communication performance is secured
