摘要： A method for detecting an electric leakage point without interrupting a power supply is provided. The method includes transmitting a unipolar direct current (DC) survey voltage signal to an electric wire of the power supply. The method includes transmitting a chain of electromagnetic wave signals generated around the electric wire to synchronize a reference time to measure an earth potential of the unipolar DC voltage signal and capture an electromagnetic tracking signal. The method includes tracing a buried route of the electric wire by analyzing the electromagnetic tracking signal according to the reference time. The method includes measuring the earth potential of the unipolar DC voltage signal on the ground according to the reference time. The method includes locating the electric leakage point by identifying a polarity of the unipolar DC voltage signal.
