5.2.8 Setting the CT Ratio
What is CT?
CT stands for "current transformer." CT is used to measure large
current to reduce the current measured to a smaller level and sup-
ply the conversion result to an instrument.
CT ratio (current transformation ratio): A ratio used to convert the
secondary current of CT to the primary current.
This ratio is used for measurement on the secondary side of an
external current transformer (CT) to convert the current mea-
sured to the primary current to be displayed.
