Because Transformer works on the princle of mutual
induction moreover it is a static device not an rotating
device and also it is only capable of stepping up or step
down of voltage so only it cant rotae like a three phase
motor

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
