Abstract: The present invention is concerned with a method of determining stationary signals for the diagnostics of an electromechanical systems in which electrical rotating machinery is used and in which at least one electrical or mechanical signal is measured during an operation of the electromechanical system. The method is used especially for condition monitoring of electric motors and generators. The method consists of measuring an analog waveform signal (S) of the electromechanical system and then manipulating that signal in various ways to obtain a frequencies spectrum, from which a vector of interest frequencies and corresponding vector of amplitudes are extracted to diagnose the electromechanical system.

Abstract: A method of inspecting equipment of a power system can involve identifying a geographical area including a presumed faulty piece of equipment with a central computer system of the power system; determining a contact (e.g., a person) at the geographical area; sending a request for inspecting local equipment in the geographical area to the person; taking a picture, by the person, of a piece of local equipment; transmitting the picture to the central computer system; and evaluating at the central computer system, whether the piece of local equipment in the picture is faulty or not.

Abstract: A method, apparatus and computer program for monitoring the condition of electromechanical systems in which electrical rotating machinery is used. The method includes measuring current and/or voltage signals, measuring an angular position of a rotating shaft of interest of the electromechanical systems or estimating the value of discrete angular position of a rotating shaft, synchronizing the current and/or voltage signals to the scaled angular displacement of the rotating shaft, dividing the synchronous electrical signals into intervals corresponding to each completed rotation of the rotating shaft, averaging a number of intervals of synchronous electrical signals to obtain an average synchronous electrical signal, extracting characteristic data of the magnitude from the values of the average synchronous electrical signal, and comparing the extracted characteristic data with a threshold limit to alarm the user when the limit is exceeded.
