Capacitor bank grounding grid heating
What is the role of the capacitor bank. Capacitor Banks generally serve two functions: (1) a series resonance branch is formed by a capacitor and a reactor to filter out harmonics of a particular frequency;For example, 12% reactors are mainly used to filter out the 3rd harmonic, and 4%~6% reactors are mainly used to filter out the 5th and 7th harmonic.
