Nettet24. feb. 2012 · What is a Line Reactor? A line reactor (also referred to as an electrical reactor or a choke) is a variable frequency drive (VFD) … Nettet9. aug. 2024 · Input line reactors are used to smooth voltage peaks or to bridge commutation dips. Line reactors also reduce the effects of harmonics on the converter and the supply system. Note: Line Impedance: The converter rated power / line short-circuit power ratio should not exceed 1% (thus for full load of the converter, the voltage …
AC Line Reactors vs. DC Link Chokes - Eaton
NettetLine reactors can be used in a number of applications to extend the life of your VFD and motor. 3% impedance reactors are generally used for the line side of a drive while 5% impedance reactors are typical on the load side of the drive.

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. The BLOCK standard product range includes series with 3%, 4% and 5 ... i can hear a whooshing sound in my ear
