Transformer Correction
Transformer correction allows you to compensate ratio and phase angle inaccuracies of the user voltage and current instrument
transformers. To enter the menu, select the T.Corr. entry from the main menu, and then press the ENTER button. For instructions
on navigating in the menu, see Viewing and Changing Setup Items.
The following table lists available options.

The ratio of the true transformer ratio to the marked
1.000
ratio.
The phase displacement, in minutes, between the
primary and secondary values. The phase angle of
0
a voltage transformer is positive when the
secondary value leads the primary value.
