About the Tettex Instruments 5288A
As a power factor / tan delta meter instrument, the Tettex Instruments 5288A is designed for demanding applications. Specifically, power factor and tan delta meters measure dielectric losses in transformers, bushings, cables, and insulation systems to assess insulation condition and predict failures. Accurate and reliable performance is essential — measurement drift or component failure can cause costly errors, compliance issues, and project delays.
Common Power Factor / Tan Delta Meter Issues We Repair
Our repair process addresses the root cause of every issue:
- Measurement bridge imbalance: identified during our multi-point inspection and corrected to restore specification performance
- Guard circuit faults: addressed with OEM-grade components and verified against traceable standards
- Hv cable deterioration: repaired by technicians experienced with Tettex Instruments instrumentation
- Temperature compensation errors: resolved through targeted diagnostics and precision repair techniques
- Test voltage source instability: diagnosed through systematic testing and resolved with component-level repair
