• When taking measurements on the secondary side of a voltage
transformer (VT), you can set the VT ratio in order to convert the
readings to their primary-side equivalents and display the
results. For a VT with a primary-side voltage of 6.6 kV and a sec
-
ondary-side voltage of 110 V, the VT ratio would be 60 (6,600 V /
110 V).
•
Since the current range is fixed at 600 V, it would be multiplied by
the VT ratio of 60
to yield a voltage range of 36 kV.
