    Sweep Frequency Response Analyzer

    measures the frequency response

    SFRA (Sweep Frequency Response Analysis) is used to assess the mechanical and electrical integrity of transformers and other electrical equipment. It measures the frequency response of the winding and core structures, helping to identify issues like: Winding Deformation: Detects physical changes in the transformer windings due to short circuits or mechanical stress. Core Movement: Identifies shifts or loosening of the core structure that could affect performance. Connection Integrity: Assesses the condition of electrical connections within the transformer. Overall Condition Monitoring: Provides insights into the aging process of the transformer and can help predict potential failures.
