1. A method comprising diagnosing a grounding system of a wind turbine generator comprising (i) a first blade as a first charge collecting structure conductively connected to a ground via a grounding path and (ii) a second blade as a second charge collecting structure connected to the ground via the grounding path, wherein the diagnosing involves an act of monitoring by comparing a first output of a first electrostatic detector connected to the first charge collecting structure to a second output of a second electrostatic detector connected to the second charge collecting structure.
