摘要

The paper offers a review of the procedure for diagnostic examination of isolated bus ducts with air insulation. Characteristic examples of isolated-phase and three-phase bus duct defects revealed during visual inspections and thermal imaging are provided. The results of lab-based measurements and acoustic location of partial discharge (PD) in the insulation systems with various defects (cracks, wet and contaminated surfaces) are discussed. Typical amplitude-frequency characteristics of the PD acoustic signals during the development of insulator defects (defect images) were obtained. The results of generator bus duct diagnostics using electromagnetic and acoustic instruments are presented.
