Abstract
A method of inspecting a wind turbine blade having an electro-thermal heating element and a surface protection layer. The method includes: exposing a test point of the electro-thermal heating element; contacting the test point to establish an electrical connection between the test point and a sensor; and electrically connecting the sensor to the surface protection layer. The sensor is operated to measure a resistance value indicative of an electrical resistance between the test point and the surface protection layer. The resistance value is analysed to determine a condition of the wind turbine blade. The invention provides a method of inspecting a wind turbine blade which enables damage or defects to be detected which may be difficult to detect by visual inspection or traditional non-destructive testing techniques.
