A Practical Guide to Sweep Frequency Response Analysis: 5 Steps to Detect Transformer Faults Early
Ler maisAbstract 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 active part, including its windings and core. This signature serves […]

Your 2025 Buyer’s Guide: 5 Essential Features in a TTR Tester to Avoid Costly Transformer Failures
Ler maisAbstract The transformer turns ratio (TTR) test is a fundamental diagnostic procedure for assessing the health of a transformer's windings and magnetic core. This examination evaluates the ratio of the number of turns in the primary winding to that of the secondary winding, a parameter determined during manufacturing. Deviations from the nameplate ratio can indicate […]

Your Ultimate 2025 Guide: 5 Critical Faults a Sweep Frequency Response Analyzer Uncovers
Ler maisAbstract A sweep frequency response analyzer (SFRA) provides a powerful and sensitive diagnostic method for assessing the mechanical and electrical integrity of power transformers. This technique functions by generating a low-voltage sinusoidal signal across a wide frequency spectrum and injecting it into one winding, while measuring the response signal at the other end. The resulting […]

The Ultimate 5-Step Guide to DC Winding Resistance Test
Ler maisAbstract The DC winding resistance test is a fundamental diagnostic procedure for assessing the integrity of power and distribution transformers. This examination measures the direct current resistance of the transformer’s windings, providing critical insights into the condition of the internal conductors and connections. By applying a stable DC current and measuring the resulting voltage drop, […]
