Transformer Correction
While using external CT meter option, transformer correction allows you
to compensate ratio and phase angle inaccuracies of the user voltage and
current instrument transformers.
The following table lists available options.

The ratio of the true
transformer ratio to the
marked ratio.

The phase
displacement, in
minutes, between the
primary and secondary
values. The phase angle
of a voltage transformer
is positive when the
secondary value leads
the primary value.
