Answer Posted / meghraj prasad
becoZ wen the main winding is exicted
frm a 1Ф supply,it produces
alternatin magnetic field instead of
RMF..nd acording to the field
revolving theory we know that any
alternating vector can be resolved in
two vectors rotating in opposite
direction and each having magnitude
equal to half of original vector..and
the vector will be rotate in such a
way that resultant will be zero so it
fails to produce net starting torque
and hence it is not self starting.,bt
i cn b made self starting...

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
