Megger OTS100AF Oil Test Set Repair
The Megger OTS100AF Oil Test Set is a dielectric oil test set – it raises a voltage across a precise electrode gap immersed in an oil sample until the oil breaks down. The result depends on the gap being exactly right and the sample being properly mixed, as much as on the voltage measurement.
June Company repairs and calibrates the Megger OTS100AF Oil Test Set for utility maintenance crews, transformer service teams, and oil testing laboratories. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common Megger OTS100AF Oil Test Set problems we fix

- Breakdown voltage readings inconsistent – usually electrode gap or sample handling rather than the measurement circuit.
- Electrode gap out of specification or electrodes pitted.
- High-voltage output not ramping correctly.
- Stirrer not operating.
- Test vessel damage or contamination.

What if it is not economical to repair? We tell you in the quote. The evaluation is free and there is no obligation to proceed.
Are the electrodes serviceable? Yes. Pitted electrodes change the result and are a normal part of restoring the set.
