Abstract

It is described a device for determining a lubrication condition of a main bearing (7) of a wind turbine (1), the device comprises a container (10) which is configured to collect a leakage lubrication oil from the main bearing (7); an outlet (11) which is configured to discharge the collected oil from the container (10) with a predetermined flow rate; an overflow passage (12) which is configured to discharge on overflow of the collected oil from the container (10); a detecting device (15) which is configured to detect an overflow of the collected oil through the overflow passage (12); and a determining device (14) which is configured to determine that the lubrication condition of a main bearing (7) is sufficient if the detecting device (15) detects the overflow of the collected oil through the overflow passage (12).
