- what: Of this study show high rates in pitch systems of both types with hydraulic systems performing slightly better than electrical (0.54 vs. failures per turbine per year) a significant variation between of different manufacturers and a tendency for higher rates for larger The paper is outlined as follows: First, an introduction of the . . .
