METHODOLOGY AND SYSTEM FOR THE DETECTION OF FERRORESONANCE IN TRANSFORMERS BY ANALYZING THEIR NOISE AND/OR VIBRATIONS

Method of premature detection of ferroresonance in transformers of the electric network by means of the analysis of signals produced by the magnetostriction coming from said transformers, such that the method is configured to avoid future damages in the transformers and in other elements of the line as a result of the overcurrent generated, and comprises the steps of: installing a suitable sensor for the measurement of the signals; carry out previous calibration tests of the sensors; obtain the standard values of the signals; start a campaign of measurements in real time until obtaining the effective value (rms) in real time; compare the effective values (rms) obtained in real time with the standard values of the different events. System for the premature detection of ferroresonance in a transformer of the electric network by measuring signals produced by the magnetostriction coming from said transformer, which comprises: a transformer, sensor for the measurement of the signals produced by the magnetostriction coming from the transformer and a data acquisition system connected to the sensor.
