Abstract

A method of monitoring and controlling a condition of a wind turbine rotor blade (110) of a wind turbine (110), the method comprising the steps of:- performing a first measurement comprising the sub-steps (S3, S4) to measure a first value of voltage and current;- calculating a first resistance value of the conductive device depending on the measured first value of voltage and the measured first value of current;- performing a second measurement comprising the sub-steps (S7, S8) to measure a second value of voltage and current;- calculating a second resistance value of the conductive device depending on the measured second value of voltage and the measured second value of current; and- comparing the first resistance value and the second resistance value in order to determine the condition of the wind turbine blade (110).
