Answer Posted / md gufran yaqub
cable size for motor is decided based on
-rated load
-starting method and current withdrawn generally conductor
size is selected 2-3 times that of rated load
-length of cable and duty type decides the cable insulation
-obviously the cable rating should not be less than
protecting device

What type of a DC motor would you use for a lift?
Assuming that a dedicated neutral earthing transformer is provided for each GT generator, when the two generators are running in parallel, has consideration been given that the earth fault current from one generator stator winding be split between the two neutral earthing transformers? If so, what adverse impact will this have on the operation of the 59N and 27TN devices?
How do you compute voltage drop and cable size over distance?
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
