A 480-V bus in an industrial plant supplying power to several feeders has a Thevenin source impedance behind the bus equal to 0.003 + j0.015 Ω/phase. A power factor correction capacitor rated 600 kVAR_3ph is connected to the bus as shown in the figure below. Determine the parallel resonance frequency and identify the precaution needed for connecting a power electronics load to this bus.
