The power grid runs on alternating current (AC) thanks to Nicola Tesla besting Thomas Edison in the “war of currents” over 100 years ago. AC won because (at the time) it was the best way to transmit power over longer distances. In recent years, advances in high-voltage direct current (HVDC) technology have made DC transmission not only economically competitive with AC alternatives, but a key enabler for increasing grid reliability and connecting low-cost and clean energy resources such as wind and solar.

Transformers are key electrical components that adapt voltage levels of electricity to reduce losses and maximize grid efficiency. In the case of wind farms, the ideal location for transformers is inside the wind turbine tower. ABB’s engineers have specifically designed the WindSTAR transformers that are extra resilient against strong vibrations and extreme and sudden movements encountered in locations such as towers of floating wind farms and off-shore platforms, while keeping them compact and light weight.
