Abstract
A system and method for dynamically adjusting capacitance added in parallel to an electrical line input for improving efficiency of an electrical system. A microprocessor monitors in real time the current and voltage wave forms of a system and selects the optimum amount of capacitance from a bank of capacitors of different values. The system is implemented at the watt-hour meter to encourage adoption of the device by utility companies and customers.
