Condition monitoring device and method for monitoring an electrical machine

A condition monitoring device for monitoring an electrical machine, the condition monitoring device comprising:

• a housing (105);
• a plurality of sensors arranged within the housing, with at least one magnetometer (140) and at least one accelerometer (150), wherein each sensor is configured to perform measurements of one or more parameters at periodic instants, wherein the measurements correspond to a measurement location determined based on a placement of the condition monitoring device relative to the electrical machine;
• a data logger (180) configured to store the measurements collected with the plurality of sensors over a time period;
• a memory (130) with condition monitoring data, wherein the condition monitoring data comprises a relation between a plurality of parameters, a plurality of conditions and a plurality of frequencies;
• a data analyzer (190) configured to:
• compare, for one or more instants, amplitude data of the measurements with the condition monitoring data, wherein the comparison is performed for the amplitude data in one or more axis and at one or more frequencies;
• detect a condition from the plurality of conditions, and at least one parameter associated with the condition, based on the comparison;
• and
• a communication unit (200) configured to transmit, in response to the detection, the measurements of the at least one parameter in the plurality of axis and at the plurality of frequencies, wherein the measurements are utilized for determining a health condition of the electrical machine.
