Line reactor short
NettetHV iron-core reactors are connected in series with the capacitor units to form a series resonant circuit with very low impedance. GE’s line of iron-core reactors are ideal for a variety of applications including capacitor banks formed by several steps, several capacitor banks connected in the same busbar, and capacitor bank installations with risk of … NettetLine reactors reduce low frequency interference (harmonics) and relieve the strain on the supply network through compensation of the distortion reactive power induced by this. The connected consumers are spared by limiting the starting current, thereby increasing their lifetime. The BLOCK standard product range includes series with 3%, 4% and 5 ...
