An A.C. motor with power factor 0.6 draws 4200 watts of real power at 240 volts from a

10 KVA Transformer. Suppose a second motor is needed and it too draws 4200 watts.

With both motors on line, the transformer will be overloaded unless a power factor

correction can be made.

(i) What power factor would be needed to be able to continue to use the same 10

KVA Transformer?

(ii) How many KVAr would need to be added to provide the needed power factor?

(iii) How much capacitance would be needed to provide KVAr correction?
