A 460-V bus in a factory supplying power to several feeders has a Thevenin source impedance behind the bus equal to 0.002 + j 0.01 Ω/phase. A power factor–correction capacitor rated 500 kVAR_3ph is connected to the bus as shown in the following figure. Determine the parallel resonance frequency with the bus and identify the precaution needed for connecting a power electronics load to this bus.
