A Practical Guide to Sweep Frequency Response Analysis: 5 Steps to Detect Transformer Faults Early
Abstract Sweep Frequency Response Analysis (SFRA) is a non-invasive diagnostic method used to assess the mechanical integrity of power transformers. By injecting a low-voltage sinusoidal signal across a wide frequency spectrum and measuring the response, this technique generates a unique frequency-dependent signature for the transformer's...
