1711Can Anyone Answer anyone of these ? Q1) why direct SOLUTION of Load Flow Studies in Not Possile ? Q2)Why majority of Buses in power system are load buses Q3)Why one of the buses in Power system is taken as reference bus (slack or swing) Bus ? Q4)Bus Admittance Matrix is a sparce (means it contains some zero elements ) matrix , give reason

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
