a) Draw and label the connection for two wattmeter method used to measure connected to STAR connected three-phase, 3-phase load. [5 marks] b) Two wattmeter connected into a three-phase, 3-wire, 220V line indicate 3kW and 1.2kW, respectively. If the line current is 20 A, calculate the apparent power and the load power factor. [5 marks] b) The input power to a three-phase motor was measured by the two wattmeter method. The readings were 5.2 kW and -1.8 kW, and the line voltage was 415 V. Calculate: (i) the total active power; (ii) the power factor; (iii) the line current.
