Feb 22, 2007 Thread starter #4 HamidEle Electrical Feb 20, 2007 309 It is a Hydro typo. 50HZ poles? Manufacturer? I don't know. We are working on an international project based on Guesses, which is driving me nuts. Upvote 0 Downvote

Apr 5, 2007 #9 00123456 Electrical Mar 13, 2007 42 Sub-transient, Transient & steaDY STATE reactance of machines are dependent on macine size. Medium size machine:- Subtransient Reactance = 0.16 to 0.24 Transient Reactance = 0.2 to 0.28 Synhronous reactance = 2.25 to 3.0 Synchronous reacance value is inversly proportional to short circuit ratio of machine. For example SC Raio = 0.4 then Xs = 1/0.4 = 2.5 Thanks Upvote 0 Downvote
