What is VT?
VT stands for "voltage transformer." It is also referred to as "PT"
(potential transformer). VT is used in high-voltage measurement to
convert (step-down) the voltage measured to a smaller level and
supply the conversion result to an instrument.
VT ratio (voltage transformation ratio): A ratio used to convert the
secondary voltage of VT to the primary voltage.
This ratio is used for measurement conducted on the secondary
side of an external voltage transformer (VT) to convert the volt-
age measured to the primary voltage to be displayed.
