HVI DTS-100A Oil Test Set Repair
The HVI DTS-100A 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 HVI DTS-100A 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 HVI DTS-100A Oil Test Set problems we fix
- Electrode gap out of specification or electrodes pitted.
- High-voltage output not ramping correctly.
- Stirrer not operating.
- Test vessel damage or contamination.
- Automatic sequence or averaging faults.
- Display, keypad or front-panel faults.
- Internal power supply faults.
- Breakdown voltage readings inconsistent – usually electrode gap or sample handling rather than the measurement circuit.
FAQs
Are the measurements verified after repair? Yes, against reference standards, with the measured results documented and returned with the instrument.
Breakdown results scatter between runs on the same sample. Why? Usually electrode gap or sample handling rather than the measurement circuit. We verify the gap as part of the service.
