TRT Advanced Series - True Three-Phase Transformer Turns Ratio Tester
TRT advanced series instruments are true three-phase, fully automatic test devices specially designed for turns ratio, phase shift, and excitation current measurements of power, distribution and instrument transformers. TRT advanced series instruments determine the transformer turns ratio by applying voltages across high voltage windings, accurately measuring voltages across the unloaded transformer windings, and then displaying the ratio of these voltages.
TRT advanced series instruments are based on a state of the art technology, using the most advanced technique available today. The test set can be used to test single-phase and three-phase transformers, both with and without taps in accordance with the requirements of the IEC 60076-1 standard.
