Abstract:
This project presents a failure analysis of power transformer using Failure Modes, Effect and Criticality Analysis (FMECA) method. With the aims to analyzing potential failure modes, possible causes, their effects and find reliability, risk priority number and rank. A general FMECA for outage causes of 500kv power transformer is presented, including the local effects and final effects, and recommended actions to avoid these outages. Assignment of risk priority numbers to various outage causes, which might occur at this voltage level are, carefully considered
