A factory has the following load with power factor of 0.9 lagging in each
phase. Red phase 40 A, yellow phase 50 A and blue phase 60 A. If the supply
is 400 V, three-phase, four-wire, calculate the current in the neutral and the
total active power. Draw a phasor diagram for phase and line quantities.
Assume that, relative to the current in the red phase, the current in the yellow
phase lags by 120° and that in the blue phase leads by 120°.
Fundimentals of Energy Systems Q8
Two wattmeters are used to measure power in a three
phase, three-wire network. Show by means of connection
and complexor (phasor) diagrams that the sum of the
wattmeter readings will measure the total active power.
Two such wattmeters read 120 W and 50 W when
connected to measure the active power taken by a balanced three-phase load. Find the power factor of the load.
If one wattmeter tends to read in the reverse direction,
explain what changes may have occurred in the circuit
