Details
The TRF-100 is Vanguard’s third generation, microprocessor-based, automatic, three phase, transformer turns-ratio tester. This lightweight, portable unit is designed for testing transformers at utility power substations.
The TRF-100 determines the transformer turns-ratio using the IEEE C57.12.90 measurement method. The transformer turns-ratio (ranging from 0.8 to 50,000) is determined by precisely measuring the voltages across the unloaded transformer windings. To ensure accuracy, the TRF-100’s measuring circuitry self-calibrates before each measurement. It requires neither adjustment nor temperature compensation. The TRF-100’s turns-ratio measurement accuracy is 0.1% or better.
Ratio Range: 0.8 – 50,000 to 1
Capable of detecting 130 different 3-phase transformer types defined by ANSI, IEC, and Australian standards
3 test voltages: 4Vac, 40Vac, and 100Vac
Phase angle and excitation current measurement
USB PC interfaces
4.5-inch wide thermal printer (optional)
