The line-to-neutral voltage at the terminals of the balanced three-phase load in the
Chapter 11, Problem 11.26(choose chapter or problem)
The line-to-neutral voltage at the terminals of the balanced three-phase load in the circuit shown in Fig. P11.26 is 1600 V. At this voltage, the load is absorbing 480 kVA at 0.8 pf lag.
a) Use \(\mathbf{V}_{\mathrm{AN}}\) as the reference and express \(\mathbf{I}_{\mathrm{na}}\) in polar form.
b) Calculate the complex power associated with the ideal three-phase source.
c) Check that the total average power delivered equals the total average power absorbed.
d) Check that the total magnetizing reactive power delivered equals the total magnetizing reactive power absorbed.
