摘要： A missing stator slot wedge (10) in an electrical machine can be detected by analysing a current spectrum of the machine in a high frequency area. A current spectrum is provided from a current measurement, and values of the current spectrum in the high frequency area used to determine whether a stator slot wedge (10) is missing or not. The conclusion can be based on values of a relative current amplitude IdB or on presence of certain harmonics in the high frequency area.

摘要： A modular crawler for inspecting a confined space that can be the air gap of a rotating electrical machinery has a main function module to which drive modules and other function modules that depend on the confined space configuration can be connected. When the confined space the air gap between the rotor and stator of a rotating machine the crawler can be used for operations such as visual inspection, wedge tapping and maintenance. The main module has cameras and on board electronics and can also have a tether to communicate with equipment located outside of the confined space, send video to that equipment and receive commands from an operator of the crawler. The drive modules have tracks that ride on the stator slots. The removable spacers between the modules are adaptive to fit the configuration that the track rides on. The other function modules provide certain other functions.

摘要： A method for identifying a fault condition in an electrical machine in which at least a stator (120) or a rotor (220) has parallel winding branches (30, 40, 50, 60) is disclosed. A measurement (230) is carried out for obtaining a set of circulating current values (240) between two parallel winding branches (30, 40, 50, 60) of which each winding branch (30, 40, 50, 60) comprises a single coil (20). A frequency analysis (250) is applied on the set of circulating current values (250) to obtain at least one frequency component (260). A fault condition (280) of the electrical machine is determined on the basis of the at least one frequency component (260).
