Transformer diagnostic testing: standards to diagnose equipment with Sweep Frequency Response analysis
BY VOLNEY NARANJO, Megger
Sweep Frequency Response Analysis (SFRA) has become a powerful tool in advanced power transformer assessments and probably one of the main and first tools used to diagnose troubled transformers or as a regular maintenance test. In addition to being able to detect problems related to the mechanical or electrical integrity of the transformer, the results can be compared to...
