摘要： 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.

摘要： A wind turbine fault detection circuit is designed to determine presence of a fault. In a described embodiment, the wind turbine fault detection circuit utilizes a magnetometer in the form of a hall-effect sensor coupled between a power converter and a ground element to measure a ground current from the power converter to obtain a real ground current. The wind turbine fault detection circuit utilizes a comparator to determine presence of a fault based on the real ground current.
