A small apartment has the following electrical loads: 4 x 60 W lamps in use 4 hours each day 4 x 1000 W heaters in use 3 hours each day 1 x 2kW immersion heater in use 2 hours each day 1 x 3 kW cooker in use 1 hours each day The tariff for the supply of electricity is a fixed charge of €20 per Month, plus an energy unit charge of €0.19 per kWh. Find the total electricity cost for 1 month (30 days). The circuit connections of a 230V 50 Hz single phase AC induction motor are shown in the figure below. The wattmeter reads 4000 Watts, the voltmeter reads 230V and the ammeter reads 20A. Draw the power triangle for the circuit and determine graphically or by calculation: The circuit power factor. The Reactive power in KVAr. The size of Capacitor needed to improve power factor to 0.99.
