NOTES
•
The CT turns ratio is ideally measured as:
Ratio
=
Vh
Vx
.
•
Since the induced voltage (
V
) is sensed through the H1-H2 terminals of
the Delta winding, this induced voltage is measured as
V
= (
3
2
)
Vh
.
•
The CT turns ratio is now measured as
Ratio =
V
Vx
or
Ratio =
(
2
3
)(
Vh
Vx
). This measured turns ratio is
2
3
higher than the actual turns
ratio.
•
The EZCT-2000 will display the correct CT turns ratio by adjusting the
measured turns ratio by
3
2
.
