Product Overview

Transformer turns ratio test is very important in order to find out the transformer has the right ratio corresponding on its rated voltage in primary and secondary. SXTTR-II is single phase, automatically test set specially designed for turns ratio, phase shift and excitation current measurements of power, distribution and instrument transformer.

Features

♦ Auto measuring transformer connection groups.

♦ Auto converting the group.

♦ Auto switching phase sequence.

♦ Auto switching measuring range.

♦ Auto calibrating.

♦ Auto calculateing relative error after input standard turns ratio.

♦ Auto cut off test voltage after one test completed.

♦ Data setting, final data saved automatically, historical data can be browsed.

♦ When test load transformer, only need to input one turns ratio.
