What sytems or methods are used for cable fault location within different countries and how good is the success rate??
In Auckland NZ in general we use the POPIE ( pool of potential in earth ) for single and multicore non screened cables.
The thumper or HV capacitor discharge is used on Ø to Ø faults or Ø to screen faults in LV and HV cables.
A-frame and signal generator used to pre locate a screen fault on long HV cables and confirmed afterwards with the Popie.
The dart is used for pre analysis of the approx fault distance.
