The current coil of a wattmeter is connected in the red
line of a three-phase system. The voltage circuit can be
connected between the red line and either the yellow
line or the blue line by means of a two-way switch.
Assuming the load to be balanced, show with the aid
of a phasor diagram that the sum of the wattmeter
indications obtained with the voltage circuit connected
to the yellow and the blue lines respectively gives the
total active power.
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.
