what happan when ac power transmitted in unity power factor
Answer Posted / rajendra
if sending end power at upf means only active power and reactive power is zero but at reciveing end side most are inductive load we need reactive power. so we never transmitted power at unity pf

How to design inductive load for 3 phase 440v and maximum 5 amps for star or delta? Can we use a 15kW, 1450rpm motor for 15kW, 960rpm apllication?If yes.how......n.if thesame motor used what`s it`s sideeefect.
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
