NettetAssuming that reactors are deployed at both line terminals, the VAR rating of a single line reactor unit can be calculated using the rated line-to-neutral voltage V. LN. and the positive-sequence reactance as follows: 2 LN 1 l1 V S φ 2•X = (8) A further consideration is whether to install the reactors on the line or the bus. NettetA reactor can be referred to as either a line reactor or a load reactor, depending on where it’s installed. As shown in Figure 1, when a reactor is placed between the power system and the VFD, it is referred to as a line reactor. Line reactors can protect the entire VFD from power system surges and transients. They also mitigate harmonic 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.
