Question

A 3-phase motor is connected to a 440V line and draws a current of 5A. If the power factor of the motor is the highest two digits in your KSU in percent ( e.g. 000123456 would be a power factor of 56%) calculate the magnitude of the total apparent power S.

Answer 1

2133.89VA

Step-by-step explanation:

Using KSU id 000123456

Apparent power = Pa = (3^1/2)*Pf*I*V

Where Pf = power factor = .56

V = 440v =voltage magnitude in the line

I = current = 5amp

So therefore

Pa =( 3^1/2) *.56* 5 *440

Pa= 2133.89VA
