line-and-load-reactors

Our RL Line/Load Reactors are best-in class power quality units with a long history of proven performance. Rugged and robust, they are un-equalled in absorbing power line disturbances that can damage or shut down variable frequency drives (VFDs) and other Sensitive equipment. They work on both the line side and load side to give you an easy solution that reduces nuisance tripping, reduces harmonic distortion and minimizes long lead effects. Improved power quality, enhanced productivity and complete peace of mind are easy with RL Line/ Load Reactors.

Features And Benefits :-

  • Ensure reliability, performance and a long service life of electrical consumers.
  • Reduction of mains harmonics and commutation notches.
  • Help to meet international power quality standards such as IEEE 519
  • Protection of motor drive electronics and dc link capacitors against mains transients.
  • Reduction of inrush and peak currents.
  • Reduction of conducted LF emission.
  • Improvement of conducted LF immunity.
  • Prevention from nuisance tripping caused by power line voltage spikes.
  • Improvement of true power factor.

What is the effect of Harmonics?

Harmonics may cause cables to overheat, damaging their insulation. Motors may also overheat or become noisy and torque oscillations in the rotor can lead to mechanical resonance and vibration. Capacitors overheat with, in the most severe cases, the risk of explosion as the dielectric breaks down. Electronic displays and lighting may flicker, circuit breakers can trip, and computer fail and meters give false readings.

Harmonic Reduction

Line reactors are a cost-effective way for the limitation of mains harmonics. The harmonics reduction capability is related to the reactor impedance. A higher impedance translates directly into lower harmonic currents, but of course also into a larger Component with a higher voltage drop and vice versa 0.5-7 % impedance reactors provide an excellent cost/benefit ratio and are particularly beneficiary in the most diverse motor drive applications.

The table below shows various reactor impedance values and their calculated effect in terms of harmonics reduction.
