The HVB10 has two different methods for fault location:
The standard mode, which provides good results for typical sheath faults faults with fault resistances of up to some hundreds of kilo Ohms and shield cross sections in the range of 25 to 50 mm2. This measurement is typically done in app 30 seconds
The high accuracy mode, which takes approximately 1 minute for the algorithm to complete, but will utilize the full potential of the measuring and control circuits of the instrument. Thus, it is ideally suited for prelocating difficult, high-resistive faults (e.g. in the inner insulation of PILC cables). An intermittent fault detection algorithm is applied to gain a result under even worse conditions with sparking faults.
