Transformers with Pre-Magnetizing System
Function
The Advanced Pre-Magnetizing System (APS) is a controlled transformer energization system designed to limit inrush current during transformer start-up. The system magnetizes the transformer core in a controlled manner, preventing core saturation and high current peaks.
The Advanced Pre-Magnetizing System (APS) is a controlled transformer energization system designed to limit inrush current during transformer start-up. The system magnetizes the transformer core in a controlled manner, preventing core saturation and high current peaks.
The APS helps reduce voltage dips, unwanted tripping of protection devices, as well as mechanical and thermal stress. The solution is particularly suitable for weak grids, generator-fed systems and applications where stable and reliable transformer energization is critical.
Benefits
- Reduced transformer inrush current
- Stable voltage levels during energization
- Reduced risk of unwanted protection trips
- Reduced mechanical and thermal stress
- Reliable transformer energization in networks with low short-circuit power
Applications
- Ship grids
- Renewable energy plants
- Data centers
- Oil & Gas industry
- Weak grid applications
- Industrial facilities
- Offshore installations
