Abstract
This paper presents a probabilistic analysis of power transformers in a power distribution company. Five years of failure-maintenance data have been collected from the operations and maintenance department of the company. Six failure modes are noted after inspection, viz., bushing failure, on-load tap changer failure, cooling system failure, winding failure, tank failure, and unidentified failure. The system is analysed using Markovian and regenerative processes, and relevant reliability indices are obtained. Sensitivity analysis is performed to assess the effect of various parameters on the reliability indicators. Relevant statistical inference and life data analysis are also presented.

Keywords
Reliability, Availability, Inspection, Markov processes, Regenerative processes.
