Leakage Field Transformer
Description
Especially in the railway sector, where maximum comfort and safety for passengers are paramount, space-saving, safe, and durable components are required. Current dips or voltage losses can cause various undesirable effects, such as loss of motor power.
The REO leakage field transformer ensures a harmonious progression of currents and voltages at the output, thus filtering harmonics and limiting ripple current. Due to the spatial separation of primary and secondary windings and the associated targeted increase of the magnetic leakage flux, the REO leakage field transformer achieves loose magnetic coupling. This combines the function of a transformer (voltage transformation and galvanic isolation) and a sine filter choke.
Selection options
- Various power classes: 50 kVA, 100 kVA, 150 kVA, and 200 kVA
- Voltage drop uk 10%, 20%, and 30%

- Winding freely selectable according to material and insulation class, and optimized for low eddy current loss
Benefits
- Space-saving (transformer and choke in one component)
- Longer motor life by limiting current peaks
- Cost-effective
- Optimized for railway operation (high degree of contamination, shock and vibration tested, salt spray and immersion bath tested)
- Rated power: 71000 – 275000 VA
- Input voltage: 210 – 1660 V
