Description: This paper describes a method for detecting faults
in the tap selector by means of vibration measurements during tap
changer operation, using envelope analysis based on Hilbert transform
and wavelet decomposition. Different failures at the tap selector
can be distinguished in the vibration signature as they are
reflected in different parts of that signature. The diagnosis parameters
allowing the most selective failure classification are found.
