A balanced Y-connected load of 100 + j50 is connected to a balanced three-phase source

Chapter 12, Problem 23

(choose chapter or problem)

A three-phase system is constructed from a balanced Y-connected source operating at 50 Hz and having a line voltage of 210 V, and each phase of the balanced load draws 130 W at a leading power factor of 0.75. (a) Calculate the line current and the total power supplied to the load. (b) If a purely resistive load of \(1\ \Omega\) is connected in parallel with each existing load, calculate the new line current and total power supplied to the load. (c) Verify your answers using appropriate PSpice simulations.
