Abstract
A condition monitoring system and method for electrical power components, in particular a transformer. A partial discharge detector unit captures acoustic signals of the partial discharge by means of an A-sensor. A processing unit captures a frequency of the partial discharges detected by the A-type sensor and a histogram module determines a temporal profile of the frequency from the frequency signal and a time signal. An analysis unit monitors the temporal profile for a fall and/or rise, preferably by means of pattern recognition. A warning signal is triggered if an adjustable threshold is exceeded. An imminent failure of an electrical power component can therefore be detected in good time and warned of; the component can be automatically disconnected if appropriate.
