while calculating demand in my company the present load in kw is 212.... there 125kvar capacitor bank is installed by spliting as 50 in departments...the diasplay in panek biard shows 175kw... how could we know the amount of kvar used to compensate the kva

1 3319How 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.

Sir, My doubt on cable sizing calculation, Load:74 KW calculated cable 1 run 50mm2. Now client asking us to reduce cable size by increasing runs. Sir, My question now when my mind strikes with 2 options 1) Divide load 74/2 = 36 and calculate cable for 36+36 making it 2 runs or 2) Simply i can divide 50mm2 /2 ie. 2 runs of 25mm2 Please suggest me sir

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.

In Dyn11 power transformer if any one of the 3 phases connected to earth in star connected side then please explain effect of the current flow in delta connected side of transformer.(In this case if one phase is shorted to ground in star connected side then we observe the current flow in two phases only not three phases in delta connected primary side. Please explain why it is so?)
