Status: Megger transformer test equipment repair covers the current TTR, MTO, FRAX, and IDAX lines plus the Delta power-factor sets and earlier models still in field service. We repair and calibrate all of them.
Common Megger Transformer Tester Problems We Fix
- Readings drifting or out of spec — precision measurement circuit calibration drift
- Winding resistance test won’t reach current — high-current source degradation on the MTO
- Won’t connect or download — USB, RS-232, or Ethernet interface failure
- Display or touchscreen blank or unresponsive
- Accuracy off across the board — internal reference standard drift
- Won’t hold a charge — battery degradation on portable units
- Lead connections intermittent — test lead connector wear

Frequently Asked Questions
How much does Megger transformer test equipment 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. FRAX and IDAX diagnostic units can run longer — we’ll tell you up front with the quote.
My TTR readings are drifting or out of spec — can you recalibrate it?
Yes. Measurement-circuit and reference drift on the TTR turns-ratio sets is repairable and recalibrated against our standards, then returned with a NIST-traceable certificate so your ratio and phase-deviation results are trustworthy again.
My MTO won’t reach its rated test current for winding resistance — is that repairable?
Yes. High-current source degradation on the MTO transformer ohmmeters is a common fault, and it’s repairable so the set delivers full DC test current and stable winding-resistance readings.
My FRAX or IDAX won’t complete a sweep — can you fix it?
Yes. We service the SFRA frequency-response circuitry on the FRAX and the dielectric-frequency-response hardware on the IDAX, restored and verified so diagnostic sweeps run and report correctly.
Megger recommends annual calibration — do you provide a certificate?
Yes. Every repair includes recalibration against our reference standards with a NIST-traceable certificate, which covers the annual calibration verification Megger recommends for these instruments.
What if my exact model isn’t listed?
We service the full range — TTR turns-ratio sets, MTO ohmmeters, FRAX and IDAX analyzers, Delta and CDAX power-factor sets, plus the CTER, MCTT, MLR, and MRCT testers. If your model isn’t in the table, pick the closest match or email us — the process is the same. A full transformer workup pairs these tests with winding-insulation checks, so we also handle Megger insulation tester repair.
Who uses Megger transformer test equipment?
Electric utilities, transformer-maintenance contractors, substation engineers, power-generation facilities, and industrial high-voltage maintenance teams rely on the TTR, MTO, FRAX, IDAX, and Delta instruments to assess turns ratio, winding resistance, winding deformation, and insulation condition. For full manufacturer details, see Megger’s TTR transformer turns ratio testers page.
