Abstract
This paper presents a vibro-acoustic method of on-line monitoring of a transformer core and winding clamping pressure. The method based on the dependence of oscillating frequencies spectra on the clamping force allows to distinguish between the core and the winding clamping pressure drop. Special software was developed for its practical application. Examples of practical application are given
