Answer / balu

There are two CT output current. 5A or 1A. These are
standard outputs.There many measuring and protective
instruments will be connected to this secondary. So these
instruments designed for the output of this current. Based
on the customer primary current, the multiple factor can be
programmed to measure primary current. So, it reduces
customization .

Answer / ashish gupta

It consider to be standard. But if we see the ratio error and phase angle error formula we observe that turns ratio ns comes out to be in denominator.So higher the turns ratio lower is the error. So higher turns ratio is obtained when secondry current is 1 amp

Answer / mukhesh

bec from t/f see relese the cts primary curent and
transfoemer ratio will give the exact 5a if any fault o
tr line the ratio willt if open will burnt ou be other
than 5 a ansd seec should not open at any time

line vltage of three phase distribution transformer is 433v and phase voltage is 250v,but we required 230v for domestic distribution,then how we reduce phase voltage of transformer
