PROBLEM TO BE SOLVED: To provide applied voltage type equipment for investigating an electric circuit accident which enables investigation without being affected by a resistance component at an accident point, and a method for investigating the accident point which uses this equipment.;SOLUTION: The applied voltage type equipment 1 for investigating the electric circuit accident includes a magnetic field sensor 3 which detects a time-derivative value of a magnetic field generated around an electric wire by a pulsed current, while the pulse current is made to flow through the wire by applying pulsed voltage on an electric circuit in an accident section by a voltage applying device 50, and an indicating part 8 which indicates the amplitude of the time-derivative value of the magnetic field detected by the magnetic field sensor 3 and the polarity at a rise time of the time-derivative value of the magnetic field. The accident point is investigated by using this equipment 1.;COPYRIGHT: (C)2009,JPO&INPIT
