5-. SOFTWARE DESCRIPTION
As is the case for all the screens, the upper part shows the name of the file containing
the test being analysed, along with the measurement mode, the fixed winding and the
position of the regulator of the variable winding.
In the central part there is a table containing the no-load current, the three types of
power (active, reactive and apparent) and the phase mismatch between voltage and current
through the high voltage winding, in all cases for each of the phases.
Below this table there are two graphs: the one on the left represents the current
through each of the phases of the high voltage winding at the regulator position to which the
data refer, and the one on the right shows a power triangle reminding the operator of the
meaning of each. The current graph will not be shown if “do not display” was selected for
the Nominal Position.
