Megger 220163 Dielectric Test Set Repair
The Megger 220163 is part of Megger’s legacy 220000-series of high-voltage dielectric test sets — rugged AC/DC hipot instruments long used in utility and industrial service, also capable of insulation-resistance (megohm) measurement. As older HV equipment, the faults are aging-HV faults: the HV transformer, regulation, and metering.
June Company repairs and calibrates the Megger 220163 for crews keeping proven legacy HV sets in service.
Common Megger 220163 problems we fix
- Output low, unstable, or won’t come up — HV transformer insulation breakdown from age, repaired for stable rated output.
- Megohm / insulation-resistance function off — the IR measurement drifting, recalibrated against standards.
- Voltage regulation drift — aging-component regulation faults, corrected.
- Meter reads wrong — metering recalibration.
- Interlock or lead-arcing faults.
FAQs
It’s an older 220163 — still repairable? Yes. The 220000-series sets are rugged and very serviceable; a repair keeps a proven instrument running for a fraction of replacement cost.
Can you still calibrate it? Yes — HV output and insulation-resistance functions are recalibrated against our standards with a NIST-traceable certificate.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
