Description
Megger PVS 100 Phase Analyzer Repair
The Megger PVS 100 Phase Analyzer is a cable fault locator – it finds where a cable has failed, usually by combining a surge generator that makes the fault arc with a receiver that pinpoints it. Two very different subsystems, and they fail independently.
June Company’s certified technicians repair the Megger PVS 100 Phase Analyzer for utility cable crews, electrical contractors, and underground distribution teams. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Megger PVS 100 Phase Analyzer problems we fix
- High-voltage output stage failure.
- Capacitor bank or discharge faults.
- Display, keypad or front-panel faults.
- Internal power supply faults.
- Surge generator not producing full output – the high-energy side, which is what makes a fault audible and locatable at all.
- TDR pulse or trace faults.
- Receiver sensitivity degraded.
- Distance measurement inaccurate.
FAQs
The TDR works but I cannot pinpoint the fault. What failed? Usually the surge generator rather than the TDR. They are separate subsystems and fail independently.
Is the high-voltage side serviceable? Yes. Output stages and capacitor banks are repairable at component level.
