1. A factory has the following electrical loads and power factor values (with a frequency of 60 Hz): • Induction motor of 16 kW with 0.8 lagging power factor. • Induction motor of 20 kW with 0.85 lagging power factor. • Load of 12 KVA with 0.8 lagging power factor. • Load of 10 KVAR with 0.85 leading power factor. A) What is the overall power factor of the factory? B) Assumer the voltage at the input to the factory is 440 V (rms). What is the rms magnitude of the current into the factory? C) A capacitor load of 6 KVAR is used. What is the capacitor value (in Farads) that is installed? D) The plot below represents the consumption of each load during a day. Assume an energy charge of 20 cents per kWh. What is the monthly demand cost? Motor 16 KW Motor 20 KW Load of 12 KVA Load of 10 KVAR off off off on on on 12 AM. 2 4 6 8 10 2 4 6 8 10 12 12 P.M.
