Methods and systems for monitoring a component of an electrical device and/or a brush of a brush holder assembly are disclosed. One method includes receiving data from a plurality of remote monitoring locations at a central control unit, where the data may be evaluated in order to monitor states of brushes or other components of an electrical device at a plurality of remote electrical facilities. For example, multiple images of a component of an electrical device may be acquired. A comparison of the images, for example, a comparative imaging technique, such as pixel-by-pixel comparison or visual observation, may then be performed in order to evaluate a condition of the brush or other component, such as a threshold and/or anomalous condition of the brush or other component.
