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.

Claim (Index 6):
The method according to  claim 1 , wherein the bearing further comprises at least one drain hole valve for selectively shutting the lubricant drain hole, and\n wherein the method further comprises the steps of shutting the lubricant drain hole by means of the drain hole valve during blowing the compressed medium through the pressure compensation hole, and opening the lubricant drain hole by means of the drain hole valve after having measured the pressure inside the bearing.
