What factors affect the reliability of a traction transformer, and how can it be enhanced?

Factors affecting reliability include thermal stress from high loads, electrical stress from voltage fluctuations, mechanical vibrations, environmental conditions, and maintenance quality. Aging insulation and degraded oil can lead to failures. Enhancing reliability involves using high-quality materials, robust design to withstand stresses, effective cooling systems, and protective devices. Implementing regular maintenance schedules, monitoring systems for early fault detection, and promptly addressing identified issues help maintain reliability. Adapting designs to specific operational environments also contributes to improved performance.
