Multiple distance locating method:
Low current impulse method: apply to the locating of the low resistance fault. Short circuit fault, open circuit fault. It also can be used in the measurement of the cable length, the intermediate joints, T joints, and cable termination joint. This method also can be used to correct the wave velocity.
Impulse current method: apply to the high resistance fault, breakdown fault. Use the current coupler to gather signal from the earth wire, it makes the user far away from the high voltage. This method is safe and reliable.
Multiple impulse method: improvement of the SIM method
