FUNCTIONAL DIAGNOSTICS OF TRACTION TRANSFORMER OF AC ELECTRIC LOCOMOTIVE USING SPECTRAL ANALYSIS METHOD

Authors/Creators

  • 1. Tashkent State Transport University

Description

The purpose of the study is to use spectral analysis for functional diagnostics of the traction transformer bushing of an AC electric locomotive, which is an important element of its asynchronous electric drive to ensure the reliability and continuity of the motion process and regenerative braking.
