Why collecting electrode of ESP to be earthed
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
