Line Reactors

Line Reactors
Line Reactors
A line reactor is an inductor wired in series between a power source and a load. It is generally used in motor drive applications to reduce harmonics, limit inrush current, and protect both the motor and the drive.

Line reactors also filter current waveforms and attenuate noise, which helps eliminate nuisance tripping and increase motor drive efficiency.

When installed on the line side of the drive, line reactors are particularly effective at protecting the drive from overvoltage tripping where impedance might otherwise be too low to counteract voltage spikes. When installed on the load side of the drive, line reactors can manage the peak voltage experienced at motor terminals, protecting motor insulation and extending the life the motor.

MTE’s RLW Line Reactor is optimally designed for peak performance in a compact and lightweight design. Lower horsepower selection allows for smaller motor protection needs, and they are suitable for application to single phase drives to provide transient protection. The RLW is primarily applied to LINE SIDE applications, but can be applied to the LOAD SIDE as well.

TCI KLR series three phase AC reactors are intended for use as input filters for adjustable speed DC drives and as input or output filters for AC-PWM variable frequency drives. Drive performance is significantly improved, the drives input rectifier is protected from failure or damage, and drive harmonic demands are tamed with the addition of a K-rated reactor. KLR reactors act as interface buffers between solid state power circuits and the line or the motor. All drives, in any application, will benefit when applied with KLR series reactors.

HPS Reactors are designed to address line-side issues associated with variable frequency drives. They mitigate voltage and current transients that can cause nuisance tripping of a drive. Reactors also minimize harmonic current levels within the drive supply circuit. When used on the output side of IGBT-based, PWM-type AC drives, HPS reactors reduce the motor operating temperature and audible noise by moderating line transients seen by the motor. Using HPS line reactors enhances the overall performance, life expectancy, and efficiency of the motor.
