Advanced Transformer Diagnostics: Sweep Frequency Response Analysis

10 May 2024
NETA World Journal

Transformer diagnostics are vital for ensuring power system reliability and longevity, with Sweep Frequency Response Analysis (SFRA) emerging as a key tool. SFRA provides insights into a transformer's mechanical and electrical integrity by analyzing frequency responses to detect deviations from its expected signature. These deviations can indicate issues like winding deformation and core movement, allowing for early detection and prevention of critical failures. SFRA's versatility across different transformer types and its capability for periodic condition monitoring make it essential for proactive maintenance and fault detection.
