What procedures are necessary for effective traction transformer maintenance?

Effective maintenance includes regular inspections, oil analysis, electrical testing, and mechanical checks. Oil samples are tested for moisture, acidity, and dissolved gases to detect insulation degradation or thermal faults. Electrical tests assess insulation resistance, winding integrity, and dielectric strength. Mechanical inspections check for leaks, corrosion, and physical damage. Cooling systems are examined to ensure efficient heat dissipation. Preventive maintenance schedules are followed to address issues proactively, ensuring the transformer operates efficiently and reducing the risk of unexpected failures.
