Hi 7anoter4,Thanks for the information and calculation. I completed the calcualtion for voltage drop including the source transformer and cable and get a resonable number.
The reason I am calulating the voltage drop is because I want to know whether the cable is capable of powering the motor and...
Thanks RRaghunath, I think you are right and I include the Station Transfomer in my calculation and get a reasonable number.
But i just have another question for the 3 phase ST, the rating is 17.8/23.7/29.7 MVA @65 Degree, Z_HX = Z_HY = 8.3% @17.8MVA, Z_XY = 16.6% @17.8MVA.
Which value transfomr...
I am doing the calculation for voltage drop at motor terminal but only get 3% voltage drop and seems wrong. Can anyone help me please?
The motor LRA is 2714A, FLC 405A, 3000HP, 4KV 3 Phase 60 Hz. But there is no transformer, it connected directly to the 4160V bus line.
Tha cable is 3 conductor...
