How much allowable difference current between on three phases Dear sir, We have a 1870 KW HT motor, 11 Kv supply,FLA-120A,2870 rpm,2-pole squirrel cage induction Motor.And stator is connected in star connection with Liquid resistance stater to limit the starting current.It has coupled with Centrifugal air compressor.My question is it is loading 73% of FLA taking R-phase 86.7 A, Y-phase-85.4A,B-phase- 78.3A.why the B phase current is that much of difference.Is it allowable, or any one tell me how much allowable current.If any method to calculate.
