Status: Megger dielectric test set repair covers the 210, 220, and 230 series — legacy high-voltage instruments still in active utility and industrial service. We repair and calibrate all of them.
Common Megger Dielectric Test Set and Hipot Problems We Fix
- Output low, unstable, or won’t come up — HV transformer insulation breakdown from age or overuse
- Voltage drifts or surges — voltage regulation circuit failure
- Meter reads wrong — metering circuit calibration drift
- Won’t energize / trips immediately — safety interlock circuit fault
- Erratic operation — control circuit component aging
- Arcing or leakage at the leads — HV cable, connector, and terminal degradation
- Overheats on longer tests — cooling fan motor failure on larger sets

Frequently Asked Questions
How much does Megger dielectric test set repair cost?
Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the instrument, you get a firm quote before any work begins — no surprises.
How long does the repair take?
Most repairs are finished within 5–10 business days of arrival, with expedited turnaround available if you need it back fast. HV transformer rebuilds can run longer — we’ll tell you up front with the quote.
These are decades old — can you still repair them?
Yes. The 210, 220, and 230 series are legacy instruments, but they’re rugged and very much repairable. Many have given decades of service, and we keep them running rather than forcing a replacement.
My output is low, unstable, or won’t come up — can you fix it?
Yes. HV transformer insulation breakdown and voltage-regulation faults are the most common failures on these sets, and they’re repairable, then verified against our reference standards so the unit delivers stable rated output again.
My meter reads wrong or the unit is out of spec — can you recalibrate it?
Yes. We recalibrate the voltage and leakage-current metering against our reference standards and return the set with NIST-traceable results on a certificate.
It won’t energize or trips the interlock immediately — is that repairable?
Yes. Safety interlock circuit faults are a routine repair, restored so the set energizes correctly while keeping its operator-protection features intact.
What if my exact model isn’t listed?
We service the full 210/220/230 range plus the HPG generators and VAX amplifier. If your model isn’t in the table, pick the closest match or email us — the process is the same. Hipot proof-testing and insulation-resistance testing go hand in hand on the same gear, so we also handle Megger insulation tester repair.
Who uses Megger dielectric test sets and hipots?
Electric utilities, cable-testing contractors, transformer-maintenance crews, switchgear testers, and industrial high-voltage maintenance teams rely on the 210/220/230-series sets to proof-test and insulation-test cable, switchgear, transformers, and rotating machines.
