Question:

A 250-kVA transformer is at full load with power factor 0.80 lagging.

(a) How many kvar of capacitors must be added to improve this power factor to 0.90 lagging?

(b) After improvement of the power factor, a new load is to be added at 0.50 lagging power factor. How many kVA of this new load will bring the transformer back to the rated kVA and what is the final power factor?
