Abstract
A method of detecting electrical failures in a wind turbine generator control system is described. The method comprises sending a test pulse through a signal path within the control system and detecting the test pulse once it has passed through the signal path, measuring a current through the signal path, and determining an input status and/or an output status of the signal path. Then, the nature of the electrical failure is identified based on a combination of the detected test pulse, the measured current and the determined input status and/or output status of the signal path.
