A food-services company with a 480 V, three-phase service entrance has the following set of loads:  A 7 ton walk-in refrigeration unit:3 COP of 1.2 and 0.78 lagging power factor  A conveyor belt system consisting of 10 continuous-duty induction motors: each 5 HP, 81% efficient, PF = 0.73 lagging  A 20 kVA T8 fluorescent lighting system with electronic ballasting (PF = 0.93 leading)  A 75,000 BTU/hr food dehydrator4 Consider the case when all systems are fully loaded. Calculate the reactive power required to compensate this customer’s load to a 0.95 lagging power factor.
