Applications

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 drive 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. (Not unlike the surge protector for your desktop PC). All drives, in any application, will benefit when applied with KLR series reactors

The KLR Line Reactor offers impedance against the flow of harmonics and other high frequencies that can cause tripping and equipment failure. Drives and other sensitive devices are protected by the KLR from electrical distortion on the line including harmonics.

Prevent Drive Shutdown

Transient voltages on the AC power lines can cause inrush currents to a VFD drive, resulting in an overvoltage condition of the DC bus. These transient voltage conditions are often caused by utility capacitor switching and will cause VFDs to shut down without warning. The addition of a KLR line reactor will limit the magnitude of inrush current, preventing trips and component failures.

Reduce Harmonic Distortion

Adding a KLR will reduce input line distortion caused by the non-linear characteristics of drives. The KLR will limit the inrush current to the rectifier, rounding the waveform, reducing the peak currents, and lowering the harmonic current distortion. High peak currents may distort the voltage waveform. The reduction of those peak currents also reduces total harmonic voltage distortion at the point of common coupling.

Improve True Power Factor

Drive input currents rich in harmonics result in a decrease in the total input power factor to the drive. The addition of a KLR will reduce the RMS current through the reduction in harmonic content, thereby improving the total power factor.
