can we use metering current transformer as protection
current transformer if not why? & if yes why?

Answer Posted / arun

Selection of CT for protection is majorly depends on the
burden limit and Kneepoint voltage at which the core of the
CT gets saturated,after which it cannot produce the
tripping emf in its core.

So check the burden of CT and kneepoint voltage.
