Megger 220164 Dielectric Test Set Repair
The Megger 220164 is a high-voltage dielectric (hipot) test set — it applies high voltage and measures leakage/current to withstand-test the insulation of cable, apparatus, and components. It combines an HV source with leakage metering, so faults span both the HV output and the measurement side.
June Company repairs and calibrates the Megger 220164 for HV test crews and electrical maintenance teams.
Common Megger 220164 problems we fix
- HV generator restoration — won’t reach test voltage or output unstable, the HV source repaired for stable rated output.
- Measurement-amplifier recalibration — the leakage/measurement amplifier drifting, recalibrated against standards.
- Internal HV arcing or leakage — insulation breakdown from stress, repaired.
- Overcurrent / trip faults — the protection tripping wrongly, corrected.
- Interlock or control faults.
FAQs
My 220164 won’t reach voltage or the leakage reading is off — fixable? Yes. HV generator and measurement faults are repairable, then recalibrated so test voltage and leakage measurement are accurate, with a NIST-traceable certificate.
Is the HV output verified? Yes — output is 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.
