Determine the all-day efficiency, Electrical Engineering

Assignment Help:

Q. A transformer has its maximum efficiency of 0.9800 when it delivers 15 kVA at unity power factor. During the day it is loaded as follows:

12 hours 2 kW at power factor 0.5

6 hours 12 kW at power factor 0.8

6 hours 18 kW at power factor 0.9

Determine the all-day efficiency.
