Leakage field transformer
Description
Especially in the railway sector, when it comes to maximum comfort and safety for passengers, space-saving, safe and durable components are required. Current drops or voltage losses can cause various undesirable effects, such as loss of engine power.
The REO leakage field transformer ensures a harmonious course of currents and voltages at the output, thus filtering harmonics and limiting the ripple current. The spatial separation of the primary and secondary windings and the associated targeted increase in the magnetic stray flux results in a loose magnetic coupling in the REO leakage field transformer. Thus, the function of a transformer (voltage transformation and galvanic isolation) and a sine filter choke is combined.
Selection options
- Various power classes: 50 kVA, 100 kVA, 150 kVA and 200 kVA
- Voltage drop uk 10%, 20%, and 30%
- Voltage translation / windings freely selectable
- Winding freely selectable according to material and degree of insulation, as well as optimized for low eddy current losses
Benefits
- Space-saving (transformer and choke in one component)
- Longer service life for motors by limiting current peaks
- Cost-effective
- Optimized for railway operation (high degree of contamination, shock and vibration tested, salt spray and immersion badge tested)
Technical data
- Nominal power : 71000 – 275000 VA
- Input voltage : 210 – 1660 V
