3.2 Setting the Measurement Parameters

Five seconds after the first (initial) message on the display, the TRT30C automatically changes the display
to the CONFIGURATION menu and the green LED lights up. By pressing
the CONFIGURATION menu and the MEMORY menu.
Press
in the HV CONFIG field to select the test mode to be performed. A list of the available test
UP/DOWN
modes is shown in tables 2 and 4.

1. If the vector group is selected, the TRT30C will perform both the true three-phase test by applying true
three-phase test voltage and the phase by phase test by applying single phase test voltages to all phases
in turn.
2. If SINGLE is chosen, the TRT30C will test a single phase transformer by applying the single phase test
voltage between 1U/H1/A and 1N/H0/N.
3. If CT is chosen, the TRT30C will test a current transformer by applying the single phase test voltage
between 1U/H1/A and 1N/H0/N.
4. If AUTO is chosen, the TRT30C will display the special menu for autotransformers to the user.
5. If the AVGD option is selected, the TRT30C will automatically detect the vector group of the transformer
under test.
6. If TRUE 3~ TEST is selected, the TRT30C will perform the true three-phase test by applying the true
three-phase test voltage.
Table 3 lists the available vector groups in this menu.
