About the ISA TDX 5000
Used across demanding applications, TTR (transformer turns ratio) testers measure the turns ratio, excitation current, and polarity of power and distribution transformers to verify winding integrity. Keeping the ISA TDX 5000 within specification protects measurement integrity and ensures compliance with industry standards.
Common TTR Tester Issues We Repair
Each repair includes comprehensive service:
- Ratio measurement accuracy drift: diagnosed through systematic testing and resolved with component-level repair
- Excitation current source degradation: identified during our multi-point inspection and corrected to restore specification performance
- Test lead interface wear: addressed with OEM-grade components and verified against traceable standards
- Display module failure: repaired by technicians experienced with ISA instrumentation
- Battery degradation: resolved through targeted diagnostics and precision repair techniques
Calibration and Performance Verification
Every ISA TDX 5000 repair includes NIST-traceable calibration covering key parameters such as turns ratio, excitation current, and polarity. We issue detailed calibration certificates documenting measured performance against manufacturer specifications.
