A method of fault location based on pulse signal injection has been promoted in this paper, which is not only independent of the following factors, such as system operating mode, topology, neutral grounding and random fault, but also the site of signal injection, the width and period of pulse are flexible and adjustable. In this paper the design scheme of software and hardware for signal source is proposed, high-pressure pulse generator is carried out by adopting C8051F310 MCU, and signal detector is designed based on the principle of electromagnetic induction.
