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

3 Answers TNEB Tamil Nadu Electricity Board,
we done magnetic balance test for 33KV /440V transformer in our company , but the ratio out is confusing us Voltage applied in RY = 440 , at RB = 320 and YB = 60 RY 440 = ( RB + YB ) 380 only Please let me know what type of problem is it.
