Mapping transformer populations: A key to optimize maintenance processes in order to minimize risks and costs

Sa？etak This article introduces a model for mapping transformer populations. The concept of mapping goes beyond a transformer condition assess- ment to include the financial risk of power disruption and downtime. Different power plant types or industrial production facilities can experi- ence significant cost increase due to production downtimes from the loss of all or a part of the transformer population. Even a single day or a few hours of lost power can have a severe economic impact depending on the function of the transformer(s). The mapping process must be modi- fied to account for these differences
