Leakage transformers – for a harmonic process of currents and voltages at the output
REO leakage transformers filter harmonics and therefore ensure a limiting of the ripple current.
Due to the spatial separation of the primary and secondary windings and the targeted enlargement of the magnetic stray field that is linked to it, a loose magnetic coupling is achieved with the REO leakage transformer. In this way, the function of a transformer (voltage transformation and galvanic separation) and a sinusoidal filter choke are combined.
- Rated power: 71000 - 275000 VA
- Input voltage: 210 - 1660 V
In railway applications, where it’s about the greatest possible comfort and safety of passengers, components are required that save space, are safe and have a long service life. Supply interruptions or voltage drops can lead to a range of undesirable effects such as the loss of motor power.
The REO leakage transformer ensures harmonized current and voltage outputs, filtering harmonics, and limiting the ripple current. With the spatial separation of the primary and secondary windings and the resulting intentional increase in the magnetic leakage field, the REO leakage transformer achieves a loose magnetic coupling.
This results in the combination of the function of a transformer (transforming voltage with galvanic separation) and a current-limiting choke.
