Answer Posted / baskaran.r
now the supply for traction is 25KV AC.connected through
pantograf. this supply is given to an onload tap changing
transformer with a secondary voltage of 800v. this through
semiconductor devices converted and applied to traction
motor. the return path is the rails through brushes in the axils

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
