Tettex 2293 Transformer Winding Analyzer Repair
The Tettex 2293 is a transformer winding analyzer — it combines turns-ratio, winding-resistance, and related measurements to characterize transformer windings, checking polarity and phase displacement across configurations. With several measurement functions, repairs touch the measurement circuitry and the test-current source both.
June Company repairs and calibrates the Tettex 2293 for transformer manufacturers and maintenance crews.
Common Tettex 2293 problems we fix
- Polarity or phase-deviation errors — the detection circuitry giving wrong results, repaired and verified.
- Ratio or resistance readings drift — measurement-circuit drift across functions, recalibrated.
- Test current won’t reach value — current-source degradation affecting winding-resistance, restored.
- Won’t connect or download — interface faults.
- Display or control faults.
FAQs
My polarity/phase results are wrong — fixable? Yes. We repair the detection and measurement circuitry and recalibrate so winding characterization is accurate again, with a NIST-traceable certificate.
Are all functions verified? Yes — ratio, resistance, and phase are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
