Baur DTA 100 C Oil Breakdown Tester Repair
The Baur DTA 100 C is an automatic insulating-oil breakdown tester — it fills a test cell, applies rising high voltage, and records the dielectric breakdown voltage of transformer oil and insulating fluids. As an HV test-cell instrument, faults center on the HV section, the test cell and electrodes, and the control electronics.
June Company repairs and calibrates the DTA 100 C for oil-testing labs and transformer-maintenance programs.
Common DTA 100 C problems we fix
- Oil contamination in the test cell — a contaminated cell scatters breakdown results; we clean and service the cell and electrodes for repeatable readings.
- Won’t reach test voltage or unstable — HV section degradation, repaired for accurate ramping.
- Inconsistent breakdown results — electrode erosion, serviced for repeatability.
- Voltage out of tolerance — regulation drift, recalibrated.
- Stirrer, cell-seal, or control faults.
FAQs
My breakdown numbers are scattered — repairable? Yes. Usually it’s a contaminated cell or eroded electrodes; we service the cell and HV section and recalibrate so results repeat to your ASTM/IEC method, with a NIST-traceable certificate.
Is the output voltage certified? Yes — verified against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
