Zusammenfassung:	The present invention relates to a system configured to monitor a condition of a rotating system comprising a main bearing, the monitoring arrangement having a first measurement device configured to be arranged at a first location in proximity of the main bearing for determining a first measurement indicative of a current flow at the first location, and a control unit connected to the measurement device. The control unit is further configured to form a first parameter based on the first measurement, match the first parameter with a plurality of predetermined current flow profiles, each of the plurality of predetermined current flow profiles being indicative of a condition of the rotating system, determine, if a matching current flow profile is found, a relevance level for the corresponding condition, and provide an indication of an alarm if the relevance level is above a predetermined threshold.
