CT are two type 1) Bar type & 2) wound type. In both case
secondary winding turns will be more, when current pass
thru the primary due to induction secondary will induced
voltage(prepotional to the ratio)will be very very high (ie
why CT should not be open circuited, cause insulation
failure and Ct damage)and reduce the quantity of current in
required preportion till the burden.
Remember the secondary current of CT is always preportional
to the primary current where as power TF is reverse.
