Elektrownia wiatrowa - co jest w środku ? Jak działa ?

A small (225kW) wind turbine from the inside, the Vestas V27 – how is the mechanics constructed? What is the maintenance process like? The machine is older, dating back to 1993, but it's simple in design, without overly complex electronics, resulting in relatively smooth operation. Jacek, the owner and service technician, and the hardest-working man I know, talks about the wind turbine. #windpower #vestas #windpowerconstruction
