Answer / sudhakar g

According to Polycab standard the current carrying for 4C 50Sqmm STEEL WIRE ARMORED cable is 133A(ground) and 142A(air)

The formula for voltage drop is

Vd=(MV*Id*L)/1000

Answer / avd

Voltage drop in cable is a function of load current. It is
simply V=IRL. where V= voltage drop in cable, I= Load
current, R = Resistance/meter length, L= length of cable in
meters.
For maximum current carrying capacity of cable please see
menufacturers catalogue.

hi all my name is ganeshkumar from Hyderabad dee According to Poly cab standard the current carrying for 4C 50Sqmm STEEL WIRE ARMORED cable is 133A(ground) and 142A(air) ok use diversity factor demand foctor, all of i know use 80% load use in ex: 142*0.80=113 amps maximum load in air in ground 133*.80=106.4 amps maximum load

what do you mean by PF correction. A motor is rated at 15 kw,415 volts, 0.7 pf and eff of 0.92. The powerfactor is improved to 0.98 by adding capacitors at the bus. calculate the current drawn by motor under full load condition before and after pf correction
