A wind energy transformer (or wind turbine generator step-up transformer) increases low generator voltage (690V to 1.2kV) to medium voltage (10kV to 66kV+). It is built compact to fit inside tower bases or nacelles, and engineered to withstand heavy vibration, variable loads, and electrical harmonics.
Key Functions
Voltage Step-Up: Raises the low electrical output from the turbine generator so it can travel safely through collection arrays.
Dynamic Load Handling: Manages frequent shifts from no-load to full-load caused by changing weather and wind speed.
Harmonic Mitigation: Filters non-sinusoidal currents produced by internal power electronics.
Design & Placement Types
Placement Location: Can sit inside the top nacelle, at the floor of the tower base, or on an outdoor pad next to the tower.
Liquid-Filled vs. Dry-Type: Uses fire-safe ester fluids or dry-solid insulation depending on environmental and safety rules.
Offshore Adaptation: Sealed and treated against salt mist, extreme humidity, and constant motion for sea installations.
