Answer / ramniveth

there is no CT to sense DC current

but it can be sensed by using two sets of rectifier units
placing one input to primary side of transformer and the
other in secondary side of the transformer.

but this is too expensive

Answer / sp

for measuring current on dc ckt. A shunt connected in the
ckt, drop of mv volt measured and shown accordingly.
2mv -10amp
4mv -20amp

Answer / vikramsena_reddys

A direct current transformer in which the primary consists
of an elongated strip of superconductive material, across
the ends of which is applied a direct current potential.
Parallel and closely spaced to the primary is positioned a
transformer secondary consisting of a thin strip of
magnetoresistive material.
