OVERVIEW:

• The motor speed regulation equipment, frequency variations, UPS units, etc. generate alterations in the network, which affect other loads in the installation of the operation of the equipment. The LR / LRB reactors connected to the input on the network side of the equipment can attenuate voltage peaks and reduce the harmonic distortion generated by the power electronics. The LR / LRB Reactors for filtering can reduce the current harmonics in any converter from 40… 50 % to values around 20 %. In addition, they reduce the shortcircuit current and increase the safety of the converter’s semi-conductors. When installed on the motor side, they can attenuate harmonic frequencies caused during switching operations.
• Low-powered reactors, LR type, are built with plates with low losses and are coiled with copper wire. The connection is achieved with adequate terminals.
• In the case of higher currents, LRB reactors are used, with a magnetic plate nucleus and multiple steel cores, which offer excellent characteristics and a low loss ratio. Copper band coils (or aluminum band, on-demand). The connections run through a plate.
• Both LR and LRB type reactors have a vacuum varnish sealing to increase the insulation, providing greater mechanical resistance and reduce the level of noise.

Application:

• The reactors of the LR / LRB series are prepared and can be used on the network and motor sides. They attenuate micro-drops and peaks during the initial connection and switching operations, and they reduce the rate of harmonics from the network current.
