The transformer sweep frequency test is a diagnostic method used to analyze the condition of electrical transformers by applying a range of frequencies to assess their response and identify potential issues such as winding deformation, insulation integrity, and core defects. This test involves using specialized equipment to sweep frequencies typically within a range of 20 Hz to several kHz while measuring the transfer function. It provides valuable insights into the transformer’s electrical characteristics, allowing for proactive maintenance and the enhancement of operational reliability. Such comprehensive testing is essential for ensuring transformers operate efficiently and safely, preventing unexpected failures and costly downtime.
