Why do we generate 3 Phase AC Supply? It is possible to
generate 4 Phase and 5 Phase explain it?
Answer Posted / hossam samir
winging is always constructed in 360 degrees angle. 3 phase
winding is built after 120 degree angle. If a 2 phase phase
wingind is designed, it is 2 , 180 degree angles winding,
which is exectly same as 2 coils in series. Similarly, 4
phase has same effects, a pair of 2phase winding.

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
