Prediction of an insulation failure in a motor

[KeenMan_DZ]

In an electric motor, it is important to detect a short circuit fault in one of the windings in its early stage. But, would it be possible to predict the moment in which an insulation failure may happen between adjacent turns in one of the windings ?

In my opinion, if we have a collection of sufficient data, representing the functioning conditions of a motor during a month, it is possible to predict its life time, or in other words, the time interval in which it my undergo an insulation failure.

What are your opinions ?

A partial failure of the insulation would change the electrical characteristics. You might be able to spot that if you had a computer carefully monitoring it.
