Abstract: The present invention relates to a dump load applied in a wind turbine generator; normally it is only operating to absorb the energy during faults. Therefore in the majority time of wind turbine generator operation, the dump load is not applied, and its health condition is unknown. This invention is about a method to check the dump load condition during normal operation.
