Chapter 2, Problem 2.52P

A balanced three-phase load is connected to a $4.16\text{-kV}$, three-phase, fourwire, grounded-wye dedicated distribution feeder. The load can be mode led by an impedance of $Z_{\text{L}}=\left(4.7+j9\right)\Omega /\text{phase}$, wye-connected. The impedance of the phase conductors is $\left(0.3+j1\right)\Omega$. Determine the following by using the phase A to neutral voltage as a reference and assume positive phase sequence:

(a) Line currents for phases A, B, and C.

(b) Line-to-neutral voltages for all three phases at the load.

(c) Apparent. active, and reactive power dissipated per phase, and for all three phases in the load.

(d) Active power losses per phase and for all three phases in the phase conductors.
