I have a single phase load (90 A 230 V) and 2 three phase loads (7 kW 400 V 3 phase/9 kW 400 V 3ph+N) connected at the same time to a three phase network.
How the 3 phase calculations (line current of each load, total line current) done in this case?
Are there any documents you recommend?
Obviously the single phase load draw 90 A from the line W.
For the three phase load 7 kW the current drawn by each line is:
I(U,V,W)= (7000)/(400*sqrt(3)*0.8) = 10 A
For the three phase load 9 kW the current drawn by each line is
I(U,V,W)= (9000)/(400*sqrt(3)*0.8) = 16.2 A
Total current drived by each line:
IV=10+16.2= 26.2 A
IW=10+16.2+90= 116.2 A
