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

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.

As we know,charged clouds(from which lightning stroke initiates)may be charged with either +ve charge or -ve charge. Now say one cluster of cloude is fully charged with +ve charge & another cluster is fully charged with -ve charge. In the sky these two cluster of charged clouds have come in such a distance that, if they come clouser by some few yeards then the lightning discharge will take place between these two cluster of clouds. Under such a situation an Aircraft came inbetween. what happend??
