Classification: CPC G | IPC G  H

Claim 0:
1. A method for detecting an abnormal event in an insulator of an electrical conductor of a medium-voltage or high-voltage electrical device, the method comprising:
acquiring a set of successive samples of a vibration signal associated with the electrical conductor,
determining a modelled value of a following sample based on the acquired set of successive samples and on a prediction model, the prediction model being obtained through machine learning of the vibration signal based on a set of samples acquired in reference conditions in which the electrical conductor is free from any abnormal event,
acquiring the following sample of the vibration signal,
calculating a difference between a value of the acquired following sample and the modelled value,
if the calculated difference is greater than a predetermined threshold, detecting an abnormal event in the electrical conductor.
