ENTER 1. If the vector group is selected, TRT03 will perform the phase by phase test by applying single phase test voltages to all phases in turn. 2. If SINGLE is chosen, TRT03 will test a single phase transformer by applying the single phase test voltage between 1U/H1/A and 1N/H0/N. - Page 10 Getting Started If the name plate voltages are not entered, TRT03 will perform the test and display the results, but it will not calculate or display the turns ratio deviation. After the name plate voltages and tap changer position(s) are entered, press to confirm a selection.
