A customer at the end of a distribution feeder is experiencing voltage regulation problems. Specifically, under high demand, when the customer's power factor is 0.90 lagging, the voltage magnitude at the customer's meter is too low. The customer comes to you, the engineer, suggesting that it may be feasible to correct this voltage magnitude problem by installing a shunt capacitor at the customer's site. Describe (a) How a shunt capacitor can help the voltage magnitude problem under the indicated conditions.
(b) What calculations you would make to determine whether this is in fact a feasible solution.
