22 and ET-41 in selected Rolling Stock Plants. The presented failure statistics provide an opportunity to adjust the maintenance cycles of selected locomotives to actual conditions. The analysis of failures in the main circuit of electric locomotives enables the exemplification of failure causes and the correction of inspection and repair cycles.Various types of electric traction vehicles are in operation at PKP, intended for performing diverse operational tasks. The designs of these vehicles vary, which results from their different operational purposes and their manufacture by various domestic and foreign producers.
Some series of vehicles have already been withdrawn from service due to wear and tear and exceeding the threshold of cost-effectiveness for their repair and operation. In their place, new series of vehicles with better operational parameters are being introduced.
The most frequently occurring failures in electrical circuits include damage to electrical machines and equipment.
Damage to electrical machines includes failures of traction motors, converters, and electric motors located on the locomotive. (…)
