Beschreibung
Zusammenfassung:	The invention relates to wind energy systems and a method of testing the rotor brake thereof. A method of testing the functioning of the rotor brake in a wind energy system is provided, wherein the measurement of the brake torque is executed by an indirect measurement of the generator torque, alternatively the actual power (440). Further, a calculation unit is provided, that contains two threshold values and is able to compare these threshold values to the values of actual generator torque alternatively to the value of actual power and the values of passed time (530). Further, a wind energy system is provided, containing said calculation unit.
