Abstract

A system for testing for wear in mechanical components of an electrical machine 2 driven by an electrical power supply 1, without the need for dismantling or removing the machine from its operating position. A wattmeter 4 which derives an electrical signal proportional to the instantaneous electrical power dissipation in the machine is connected between the power supply and the machine. The output of the wattmeter is applied to a spectrum analyser 5 to produce a power frequency spectrum which is related to the condition of mechanical components of the machine, such as bearings, that affect the performance of the machine and allows inspection of component condition to be made. <IMAGE>
