Status: Megger oil test set repair covers the current OTS60, OTS80, and OTS100 ranges plus the OCR reclosers and earlier OTS models still in service. We repair and calibrate all of them.
Common Megger Oil Test Set Problems We Fix
- Won’t reach test voltage or output unstable — HV transformer degradation from repeated breakdown events
- Inconsistent breakdown readings — electrode erosion from cumulative arcing
- Test voltage out of tolerance — voltage regulation circuit drift
- Oil leaking from the test cell — vessel seal failure
- Erratic operation or won’t sequence — control circuit component failure
- Stirrer not turning — stirring motor failure
- Display blank or printer not working — output mechanism faults

Frequently Asked Questions
How much does Megger oil 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.
My OTS won’t reach its rated test voltage or the output is unstable — can you fix it?
Yes. HV transformer degradation from repeated breakdown events and voltage-regulation drift are the most common OTS faults, and they’re repairable, then verified against our reference standards so the set ramps to full rated voltage accurately.
My breakdown readings are inconsistent — is that the electrodes?
Often, yes. Electrode erosion from cumulative arcing causes scattered or low breakdown results. We service the electrode system and the HV chain, then recalibrate so results are repeatable to your test standard.
My oil vessel is leaking — can you repair the cell?
Yes. Test-cell seal leakage is a routine repair, restored for a clean, contained vessel that holds the proper electrode gap.
My readings are out of spec — can you recalibrate and certify it?
Yes. Every repair includes recalibration against our reference standards, and the set comes back with a NIST-traceable calibration certificate. We verify output voltage so your ASTM D877, D1816, or IEC 60156 results are trustworthy.
Do you service sets used for ester and silicone oils, not just mineral oil?
Yes. The OTS range tests mineral, ester, and silicone insulating fluids, and we repair and calibrate the set regardless of which fluid type you run.
What if my exact model isn’t listed?
We service the full OTS line — PB, AF, and SX configurations — plus the OCR recloser testers. If your model isn’t in the table, pick the closest match or email us — the process is the same. Oil condition and winding insulation are two halves of the same transformer health check, so we also handle Megger insulation tester repair.
Who uses Megger oil test sets?
Transformer-maintenance crews, oil-testing laboratories, utility insulation programs, power-generation facilities, and high-voltage equipment maintenance teams rely on the OTS series to measure the dielectric breakdown voltage of insulating oil and decide whether it needs filtering, reconditioning, or replacement.
