Description
Tettex TTR 2796 Transformer Turns Ratio Repair
The TTR 2796 is a transformer turns-ratio tester in the same family as the 2795, used to verify ratio, polarity, and phase deviation on transformer windings during commissioning and maintenance. As a precision measurement set, its faults track the measurement circuit, excitation source, and connections.
June Company repairs and calibrates the TTR 2796 for transformer crews and testing teams.
Common TTR 2796 problems we fix
- Ratio measurement drift — measurement-circuit drift out of spec, recalibrated to accurate ratio readings.
- Excitation-source degradation — affecting the test signal, repaired and verified.
- Test-lead connector replacement — worn leads causing intermittent readings.
- Interface/download faults — PC connection issues.
- Display or control faults.
FAQs
My 2796 ratio readings won’t hold — repairable? Yes. We repair the measurement and excitation circuitry and recalibrate so readings are stable and accurate, documented with a NIST-traceable certificate.
Is it certified after service? Yes — verified against our reference standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
