Megger HVB10 High-Voltage Bridge
The Megger HVB10 High Voltage Bridge is designed for precise fault location in long cables, including sheath and cable faults. It features a dual-mode operation, offering standard and high accuracy modes to adapt to various fault conditions effectively. The device integrates advanced measurement technologies to ensure accurate diagnostics and is equipped with an "Easy Go" operating system for simplified operation. Ideal for utility companies, the HVB10 helps reduce downtime and facilitates efficient maintenance of power, pilot, and communication cables.

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.
