Wind energy systems rely on efficient electrical infrastructure to convert and transmit power reliably. the critical components in wind systems are liquid immersed power transformers, which step up or step down voltage for optimal transmission.
Wind turbine converts wind cinetic energy into mechanical energy used by electrical generator that is connected to the low voltage side of a step-up transformer (directly or by an electronic power converter).
Two different types of plants are available:
On-shore plant
On land, that is the most common.
Off-shore plant
Installed several kilometers far from the coast and then connected to the land (or to the oil & gas
The transformers used in this field has custom designed to the different turbine requirements and country regulations maintaining the highest degree of safety, efficiency and eco-friendly design. They have compact design, vibration resistance and highest reliability and efficiency for installation in the nacelle or inside the tower according to the wind turbine manufacturers design requirements.
Typically these transformers are cast resin or liquid immersed filled with silicone or midel oil.
When Varelen prepares a solution for windmill is particularly focused on:
Flame retardant, short-circuit proof and mechanically strong, Fluid-immersed distribution transformers withstand even the harshest conditions. They transform the voltage from the generator to the medium-voltage level needed for transmission. Varelen offers custom Fluid-immersed distribution transformers for wind farms and solar farms
