HVB10

<p>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.</p> <p>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).</p> <p>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.</p> <h3>Key features</h3><ul><li>Test insulation and cable sheaths with up to 10 kV DC (negative polarity) to identify weak points early.</li><li>Pre-locate difficult faults automatically using the voltage drop method with bipolar measurement, helping eliminate external influences such as thermo‑electric and galvanic effects.</li><li>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.</li><li>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.</li></ul>
