NAME : DV Power TRT63B Turns Ratio
MAKE : DV Power
MODEL : TRT63B
Description : TRT63B is a true three-phase, fully automatic test set specially designed for turns ratio, phase shift, and excitation current measurements of power, distribution and instrument transformers. TRT63B determines the transformer turns ratio by applying voltages across windings, accurately measuring voltages across the unloaded transformer windings, and then displaying the ratio of these voltages.
