- A wattmeter has its current coil connected in the yellow line, and its voltage circuit is connected between the red and blue lines. The line voltage is 400 V and the balanced load takes a line current of 30 A at a power factor of 0.7 lagging. Draw circuit and phasor diagrams and derive an expression for the reading on the wattmeter in terms of the line voltage and current and of the phase difference between the phase voltage and current. Calculate the value of the wattmeter indication. ANS: . Line amperes × line volts × sin φ = 8750 vararrow_forward4. The circuit shown below shows an infinite impedance (open circuit) in phase B of the Y-connected load. Find the phasor voltage VOB if the system is 208 V, sequence ABC. -j100 Q 100 Ω B 5. Three identical impedances of Z = 15260°2 are connected in Y to a three-phase, three-wire, 240 V, ABC system. The lines between the supply and the load have impedances of 2 +j 1 Q2. Find the line voltage magnitudes at the load. Find the new values when a set of capacitors with reactance of -j10 Q (Y-connection) is connected in parallel with the load. Draw the vector diagram for the load current, the capacitor current and the system line current.arrow_forward1.
