Q2
(a) Based on the relationship between the line and phase value of currents and voltage, show
that the active power input to a three-phase balance load is v3VIcoso, where V and I are
line quantities.
(b) A balanced Y-connected load has phase voltage of 230 V and positive phase sequence.
The impedances Za, ZB, and Zc are 10430° n, respectively.
(i)
By taking VaB on the load side as a reference, determine all the line currents and
phase voltages.
(i1)
Determine total real power, P, total reactive power, Q and total apparent power,
S of the system.
(111) Total real power of the loads can be measured using two wattmeter methods.
Draw the connection of the two wattmeters if their current coils are in line A
and C, respectively. What is the total real power measured by each wattmeter?
Prove and compare the value with Q2(b)(i).
