SUMMING WATT-HOUR TRANSDUCER Abstract of the Disclosure A summing watt-hour transducer is connected to a three- phase power line to monitor the energy being supplied to one load, and is connected to an ordinary watt-hour transducer that monitors energy supplied to a second load. A summing integrator circuit sums and integrates signals derived from the power line and the ordinary watt-hour transducer to obtain a voltage proportional to a unit of total energy demand. The summing operation is triggered by a signal from a control circuit that is responsive to contact closure pulses from the ordinary watt-hour transducer. Output signals from the summing integrator circuit are converted to contact closures for input of energy demand signals to an energy demand/schedule controller.
