ABSTRACT:
A wind turbine is provided having a gearbox containing a lubrication medium, a pump for circulating the lubrication medium, and a gearbox lubrication suction pipe for transporting the lubrication medium from the gearbox to the pump. A heater is in thermal connection to, at least a portion of, the gearbox lubrication suction pipe. This heater is used to heat the lubrication medium contained within the gearbox lubrication suction pipe to a temperature where damage to the pump is avoided.
