voltages; otherwise, they will be line-to-line voltages.
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.
Label Parameter Options Default Description
Ratio V1-V3 V1-V3 voltage
transformer
ratio correction
factor
0.700 to 1.300 1.000 The ratio of the true
transformer ratio to the
marked ratio.
Angle V1-V3
V1-V3
transformer
phase angle
error, minutes
-600 to 600
0 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.
Ratio I1-I3 I1-I3 current
transformer
ratio correction
factor
0.700 to 1.300 1.000 The ratio of the true
transformer ratio to the
marked ratio.
Angle I1-I3
I1-I3
transformer
phase angle
error, minutes
-600 to 600
0 The phase
displacement, in
minutes, between the
primary and secondary
values. The phase angle
of a current transformer
is positive when the
secondary value leads
the primary value.
Using PAS
Select General Setup from the Meter Setup menu, and then click on the
Transformer Correction tab.
