A strategy for power transformer spares
With long lead times on power transformers, reliability impacts and cost implications make transformer spares a critical decision for utilities that own and maintain this equipment. For a given fleet of power transformers, there are a lot of elements that come into play when it comes to selecting the right quantity of spares. While most power transformer populations are a mixed bag (have a wide variety of loadings, criticality, ages, and asset condition), aging infrastructure and system reliability remains a critical concern for many utilities. The primary concern is multiple catastrophic failures combined with high replacement costs and long lead times for these critical components. So what is the right number, and how do we get to it?
