HVI PAR-1680FC5 AC Dielectric Tester Repair
The HVI (High Voltage Inc.) PAR-1680FC5 is an AC dielectric (resonant) test set — it generates high-voltage AC to withstand-test cable, switchgear, and apparatus insulation, with the resonant design efficiently delivering high voltage into capacitive loads. As HV-generation equipment, faults concentrate in the HV resonant section, regulation, and metering.
June Company repairs and calibrates the HVI PAR-1680FC5 for utilities, cable manufacturers, and switchgear service companies.
Common HVI PAR-1680FC5 problems we fix
- Won’t reach test voltage or output collapses — HV resonant-section or output-stage failure, rebuilt for full rated AC output.
- Won’t tune/resonate into the load — the resonant tuning that delivers voltage into capacitive loads, repaired.
- Leakage/voltage metering off — measurement drift, recalibrated against standards.
- Internal HV arcing or leakage — insulation breakdown from stress.
- Control or interlock faults.
FAQs
My PAR won’t reach voltage into my cable load — fixable? Yes. That often points to the resonant tuning or HV section; we repair it so the set tunes and delivers full rated voltage, verified with a NIST-traceable certificate.
Is the metering certified? Yes — voltage and leakage verified against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
