CHAPTER 3 Harmonic blocking reactors
between capacitor and inductance impedances of the electrical system. By adding an appropriately rated series reactor to the power capacitor, both elements form a low-pass resonant circuit (usually below the 5th) which prevents higher order harmonics to flow into capacitors. ICAR harmonic blocking reactors are made of high-class
