What will be the direction of rotation of a Alternator in case it goes in motoring action when connected with grid ?
6 13155There is no such thing as a Generator. All power generating devices are Alternator since both generate alternating current since this is the only way electrical power can be generated. In "generators" the alternating current is converted into DC inside the housing of the "generator" in order to give out DC Do you agree? If not please educate me. How else is DC generated if not like above?

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
