why the electric train touches only one conductor n where is the neutral n it will be running 3-phase or 1-phase?
3 6841what are the oils used in transformers cooling? n which type transformer is used in power systems?
1 4355the electric traction poles having 3 cables n two cables touches with a insulator (or any) another one separated but it will be running 1-phase why?

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
