Description
TRM350 uses inverter powered source which can eliminates influences of harmonics during measurement. 3 phase output voltage adopted to improve test speed. and the wiring group can from 0-11 can be selected
It has high and low voltage reverse connection protection, transformer turn short circuit protection, tap switch failure protection, output full short circuit protection
After inputting the rated parameter, it can automatically measure the transformer ratio value, error value and on-load tap-changer position. And vector group can be selected before the test.
