Hi the question in the photo but can you please just find the

percentage voltage regulation with the

power factor 0.78 lagging

 

Q1. For 'Load at Unity Power Factor' example discussed in the lecture (see figure below), find power to load, percentage voltage regulation, power losses and percent efficiency if the power factor is 0.78 lagging. Compare your results to example discussed in the class. Iline, 480:240/120 Ioad ll 1.04 Ω j0.62 Ω 120V Vin 13.5 k2. N 240 V Rated @unity 120V ll 8.

A 10 kVA, 480:240/120 V supplies 240 V at rated load Unity Power Factor Rated Load? – means we have to supply 10 kVA no matter what the power factor is!
