A power transformer is usually an apparatus with very good reliability requiring relatively low maintenance.
Sometimes high forces occurred during transportation, or forces during the high current electrical faults could be the reasons for the serious mechanical movement of the active parts inside the transformer.
The Sweep Frequency Response Analysis (SFRA) has become an important standard test and provides comprehensive information about the mechanical and electrical integrity of the active part of power transformers.
Electrical as well as geometrical changes in the magnetic core, the winding assembly, and the clamping structure, can be detected by comparing the actual measurement with a reference measurement.
The main focus of this webinar will be an introduction to SFRA, testing procedures, and case studies.
The webinar will be held in the English language.
