Powering Progress together: Strategic Green Hydrogen Project.
We are proud to share that the first prototype of an electrolysis key project plant has been recently successfully tested in combination with coverter system.
The solution features a three-winding transformer, housed in a single-tank liquid-immersed system, specifically designed to meet the demanding requirements of converters based power supply systems.
Key Technical Specifications:
• Rated Power: 13,000 / 2x6,500 kVA
• Primary Voltage: 33 kV – 3 plug-in terminals
• Secondary Voltage: 2x(800…550) V – 2x(2x3) phase bars on the short side of the tank, with flange for direct coupling to LV busduct systems
• Configuration: MV side connected to MV bus / LV sides connected to high-frequency converters
Highlights:
◦ Low noise under full-load operation
◦ Compact footprint for space-constrained installations
This project represents a significant step forward in transformer design for high-efficiency industrial applications, combining electrical performance, mechanical integration, and acoustic optimization.
A sincere thank you to our customer for trusting SEA SpA with this challenge and for the collaboration throughout the development process.
