Answer / s.g.jayakumar
MCB is (Miniature circuit breaker) constant current rating
Example:2A,4A,6A,10A,16A but VCB is (variable circuit
breaker) Example:1.6A to 2.5A,2.5Ato4A

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
