Varelen has supplied oil immersed rectifier transformers 12500kva  for a green hydrogen production facility . power transformer solution helps ensure a reliable power supply for hydrogen production from renewable energy, contributing to a sustainable energy future.

Power transformers are a critical component of the electrolysis process used to generate hydrogen from renewable sources. The system supports a stable power supply and is designed for high efficiency, harmonic resistance, and low energy losses—key factors for the industrial-scale production of green hydrogen.

Hydrogen Transformers Features:
The power transformers used in the electrolysis process are usually similar to those used in the renewable energy sector.

• Ability to adapt to high currents with low voltage level
• High-temperature fluid used as standard
• Possibility to configure the mechanical interface according to the required integration
• High efficiency and environmentally friendly
• High overload capacity
• Fully customised according to customer needs
• Harmonic suppression: Through multi-pulse rectification design (such as 12-pulse and 24-pulse), oil-immersed transformers can be matched with rectifier circuits to reduce harmonic content   and minimize interference to the power grid.

Our high power rectifier transformers are meticulously designed and constructed to meet the rectifier interface requirements for electrolysis. Our deep understanding of these requirements ensures seamless integration and optimal performance of our transformers for hydrogen applications.

Frequently Asked Questions (FAQ)

Q1, What is an oil-immersed transformer used for in hydrogen projects?

An oil-immersed transformer in hydrogen projects is primarily used to supply stable electrical power to electrolysis systems and rectifier units. It converts grid voltage to the required level for hydrogen production equipment while ensuring reliable operation under continuous high-power industrial loads.

Q2, Why are oil-immersed transformers commonly used in hydrogen production plants?

Oil-immersed transformers are widely used in hydrogen production plants because they provide excellent cooling performance, high insulation strength, and long operational life. These features make them suitable for electrolysis systems that operate continuously with large electrical loads.
