Phenix Technologies 475-20 Hipot Tester Repair
The Phenix 475-20 is an AC/DC dielectric (hipot) test set — a 20 kV-class unit that applies high voltage and measures leakage current to withstand-test insulation on cable, components, and apparatus. It combines a regulated HV source with precision leakage metering, so its faults span the HV output and the measurement side.
June Company repairs and calibrates the Phenix 475-20 for HV test labs and electrical maintenance teams.
Common Phenix 475-20 problems we fix
- HV output-stage rebuilds — won’t reach test voltage or output collapses, rebuilt for stable rated AC/DC output.
- Leakage-current sensor recalibration — the metering your pass/fail depends on, recalibrated against standards.
- Voltage won’t regulate — 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 hipot repair. We recalibrate the leakage sensor 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.
