HVI PFT-301CM Hipot Tester Repair
The HVI PFT-301CM is a higher-output AC/DC dielectric hipot test set from High Voltage Inc. — built for withstand-testing larger apparatus and cable where more current and voltage capacity are needed. As HV-generation equipment with precision leakage metering, repairs span the HV output stage, the ground/return path, and the measurement side.
June Company repairs and calibrates the PFT-301CM for HV test labs and electrical maintenance crews.
Common PFT-301CM problems we fix
- HV output-stage rebuilds — won’t reach rated voltage or output collapses under load, rebuilt for full AC/DC output.
- Leakage-current sensor recalibration — the measurement your pass/fail depends on, recalibrated against standards.
- Ground/return circuit faults — the return path that the leakage measurement relies on, repaired.
- Voltage-regulation drift — corrected for stable output.
- Internal HV arcing or interlock faults.
FAQs
My PFT-301CM output is weak under load — repairable? Yes. HV output-stage rebuilds are routine; we restore full rated AC/DC output and recalibrate the leakage metering, with a NIST-traceable certificate.
Is the leakage measurement certified? Yes — the sensor is recalibrated and 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.
