I hope the question relates to current transformer.If the secondary is open circuited,the whole of the primary current will work as magnetising current.A dangerously high voltage will be induced in sec wdg bcoz the sec has large no of turns as compared to primary in CT.And this high voltage gives fatal shocks and for this reason secondary of CT must always be earthed.

in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com
