Beschreibung
Zusammenfassung:	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.
