HVB10 high-voltage bridge for cable fault location
Measures resistance (not impedance) to help locate faults on long, cross‑bonded and submarine cables.
Choose fast standard mode for typical sheath faults, or high‑accuracy mode for high‑resistance and intermittent faults.
One instrument for 10 kV testing, pulsed DC/A‑frame pinpointing, and controlled burning to stabilise faults.
Bipolar measurement reduces external influences, connection check highlights wiring issues, and USB logging supports reports.
About the product
HVB10 is a high-voltage measuring bridge for utilities and cable specialists who need reliable pre-location when reflection-based methods struggle – for example on very long HV/submarine cables, cross-bonded systems, or high-resistance faults.
What you can do with HVB10
- Test insulation and cable sheaths with up to 10 kV DC (negative polarity) to identify weak points early.
- Pre-locate difficult faults automatically using the voltage drop method with bipolar measurement, helping eliminate external influences such as thermo‑electric and galvanic effects.
- Pinpoint sheath faults using either pulsed DC for the step‑voltage method (with a suitable receiver) or a 3 / 4.8 Hz A‑frame signal.
- Burn faults (controlled) with selectable current limit and up to 200 mA continuous output current for short periods, to stabilise intermittent or “drying” faults before pre-location.
Designed for long, high-capacitance cables
The built-in discharge unit supports test objects up to 25 µF, with capacity checking to protect the instrument. Power is available from a wide‑range mains input (88–264 V, 50/60 Hz) or the integrated rechargeable battery for around 2 hours of operation (typical conditions).
Faster, safer field workflow
HVB10 uses Megger’s EasyGo operation with a rotary encoder and touch screen, detects incorrect hook‑up, and stores test/log data to USB for reporting and traceability.
