Abstract: A device for measuring an amount of capacitance to correct a power factor of a running electric motor includes a three-phase bus for connection to the electric motor; a metering device operably connected to the three-phase bus for displaying KVAR, the metering device including a display for displaying power factor, voltage, current, frequency, active energy, reactive energy, active power, reactive power, apparent power or maximum demand of the motor; a plurality of switched delta-configured capacitor circuits operably connected to the three-phase bus, each of the switched delta-connected capacitor circuits having different capacitance values; and a plurality of switches, each of the switches being operably associated with a respective one of the switched delta-configured capacitor circuits to connect to the three-phase bus the respective one of the switched delta-connected capacitor circuit to minimize the KVAR reading.

Abstract: An apparatus designed to accurately measure the capacitance required in order to optimize the power factor of single phase and three phase induction motors. Capacitor circuits are interruptably connected to the busses by means of push-button switches. Leads electrically connected to the busses are attached to a calculator unit which is, in turn, electrically connected to the load leads. The calculator unit displays in digital figures the actual operating conditions of an induction motor and the capacitance required for power factor optimization. The correct capacitance required to increase power factor in the 99% to 100% range is determined by either: (1) pushing a switch or a combination of switches, or (2) pushing the automatic mapping switch.
