System Overview:
TRT3x 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.
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.
DV-Win Software:
The DV-Win software is included in the purchase price, and all its updates are free of charge.
The software allows full control of TRT3x functions from a PC, creating and storing test plans, and downloading test results from the instrument’s internal memory.
All results are presented both numerically and graphically, for an easy and convenient analysis.
Test results can be directly exported to excel document.
Customized test report can be generated, edited, saved in several file formats including pdf, and printed.
