Answer / ram

by measuring resistance of primary coil (pt has high resistance-ct has low resistance)

Answer / arun

ct is incoming & outcoming wire .pt having only one wire either it is recieving or incoming

Answer / vikas

PT primary circuit is grounded always. you can identify
easly. there are no other way to identify without seeing
rating plate

Answer / savarkarshriram

If connected in circuit it can be easily identified whether
it is connected in series or in parallel. The one which is
connected in series is CT and in parallel is PT. Also it
can also be identified because PT comes with a fuse
arrangement in primary path whereas in CT you wont fuses.

Answer / mahaveer.r.d

To measure current in ckt, need to connect CT primary in
series with load. so terminal will be two per phase in/out.
To measure voltage, PT need to connect at across two phases
so no of terminals required at HT side one for each phase
so its essay to identify looking at no of terminals
