Answer Posted / r. anand
CT stands for current transformer. It is nothing but a step-
up transformer used to measure current, the primary of
which have very few turns and the secondary with 1000s of
turn, by this only 1/1000 of the current in the primary
reaches the secondary and so an Ammeter with much lower
value, calibrated to a higher value may be used. The
secondary of a CT should not be left open.
