Turns ratio verification calibrator TRTC is designed to be a reference transformer for the accuracy verification of three-phase transformer turns ratio testers. It’s intended to be used with DV Power TRT series of instruments.
This accessory instrument is available for both single-phase and three-phase test. It ranges up to 4800 transformer turns ratios and test voltages from 1 V to 250√3 V.
The available turns ratios are 1, 10, 20, 50, 200, 800, 2400 and 4800. The turns ratio calibrator achieves the best accuracy of the 0,2 %.
