Effects of Harmonics for power factor correction Capacitor Banks
Do the harmonics in your distribution system is a potential threat for your capacitor bank? Yes. When a capacitor bank is installed in a harmonic rich environment, they create a low impedance path and magnify the magnitude of current and voltage harmonics in a system resulting in parallel resonant effect. With this resonant phenomena, the […]
