How can calculate the efficency of the rectifier. input
240V AC, current 5 amps,P.F 0.98, Output is 54 V DC,62.6 A.

Answer Posted / shrinivas

As you are saying the input 240V, 5 Amps and the PF is

The input power becomes 1176 and for output of 54V and
62.6A...then putput power is 3380.4 therefore the Efficency
becomes (1176 / 3380.4) x 100 = 34.79%

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
