A transformer is a static electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a varying electromotive force (emf) or “voltage” in a second coil. Power can be transferred between the two coils through the magnetic field, without a metallic connection between the two circuits. Faraday’s law of induction discovered in 1831 described this effect. Transformers are used to increase or decrease the alternating voltages in electric power applications.

Reactor / Choke

As a reliable solution for adjustable speed drives, AC to DC converters, active front ends and frequency inverters, line reactors reduce harmonic current distortion and absorb voltage transients. They help to reduce harmonic currents that flow through facility transformers and onto the upstream power system (network). They increase line impedance so as to efficiently reduce the adverse effects of voltage transients such as drive over-voltage tripping or rectifier damage and they can reduce the impact of voltage notching due to SCR controllers.

The line reactor’s impedance can also limit the startup and peak currents associated with energizing converters thus protecting your electronics. Additionally, peak current in capacitor circuits can be dampened.
