Turns Ratio Tester | TRT Advanced Series

Turns Ratio Tester – Overview

TRT advanced series 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. It determines 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. 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. It has a very high ability to cancel electrostatic and electromagnetic interference in HV electric fields.

Turns Ratio Tester  – Features

  • Automatic vector group detection
