Answer Posted / aee_rt
C.T. is current transformer, its similar to Transformer bur
is made for low burden(i.e load).It is used to step down
the current level in order to use it for measurement and
for providing protection, coz current in terms of kilovolt
cannot be measured.Its seconadary output is fixed at 1A or
5A. Its manufactured for particular ratios and its
secondary current is proportional to primary current.
When its connected in circuit, please be sure that none of
secondary terminals are open n check for its insulation
resistance.
