Abstract
A method of monitoring the amount of lubricant inside a bearing of a wind turbine is provided. The bearing includes a lubricant for reducing wear and fatigue of the bearing, a seal for minimizing the amount of lubricant which is leaking out of the bearing, a ventilation device with at least one pressure compensation hole for enabling a pressure compensation between the sealed bearing and the ambient, and a lubricant drain hole for enabling lubricant to exit the bearing in a controlled manner. The method includes the steps of blowing a compressed medium through the pressure compensation hole into the bearing; measuring the pressure inside the bearing; and determining the amount of lubricant inside the bearing based on the measured pressure.
