in wind mill use 2100 kw asychronous generator ( induction generator ) rotor voltage : 3300,stator voltage : 690, rpm : 1511 type : MRL063E04 ' we check rotor resistance magger value found following. R-EARTH - 00 M.OHM,Y-EARTH-34 M.OHM,B-EARTH- 33M.OHM R-Y: 31 M.OHM, Y-B: 00 M.OHM,B-R :33 M.OHM HOW CAN I TAKE DECISION?pls ans. quickly
A 3-PHASE TRANSFORMER IS USED TO STEP-DOWN THE VOLTAGE OF A 3-PHASE, 11KV FEEDER LINE. PER-PHASE TURNS RATIO IS 12.FOR A PRIMARY LINE CURRENT OF 20A, CALCULATE THE SECOUNDRY LINE VOLTAGE, LINE CURRENT AND OUTPUT KVA FOR FOLLOWING.A)STAR- DELTA.B)DELTA-DELTA.
how we sesign the transformer give some specifion regarding design of transformers
why we not used 11kva as a direct our electrnics component.
Why should we hire you over the others waiting to be interview?
1.why should we connect the measuring instruments in l.v side in short circuit test of a transformer? 2.why the power factor is less in open circuit test of a transformer?
