Abstract

This article examines the principles of diagnosing locomotive power electrical circuits using the USTA microprocessor-based control system during rheostatic testing. The structure of the system, control algorithms, monitoring of analog and discrete signals, and verification of diesel-generator characteristics are analyzed. The study demonstrates that the application of USTA improves regulation accuracy, enhances protection reliability, and simplifies diagnostic procedures during maintenance.
