HVI PFT-103CM Hipot Tester Repair
The HVI PFT-103CM is a portable AC/DC dielectric hipot test set from High Voltage Inc. — it applies high voltage and measures leakage current to withstand-test insulation on cable, switchgear, and apparatus. Combining a regulated HV source with precision leakage metering, its faults span both the HV output and the measurement side.
June Company repairs and calibrates the PFT-103CM for HV test crews and electrical maintenance teams.
Common PFT-103CM problems we fix
- Won’t reach test voltage or output unstable — HV output-stage failure, repaired so it delivers stable rated AC/DC voltage.
- Leakage-current readings off — the metering your pass/fail depends on, recalibrated against standards.
- Output won’t regulate — voltage-regulation faults, corrected.
- Internal HV arcing or leakage — insulation breakdown from stress.
- Interlock or control faults — won’t energize or trips immediately.
FAQs
My leakage reading is off — fixable? Yes, and it’s the critical repair on a hipot. We recalibrate the leakage metering against our standards so the number you certify against is accurate, with a NIST-traceable certificate.
Is the HV output verified? Yes — AC and DC output are checked along with the metering.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
