SF6 End-of-life analysis for Transformers

SF6 End-of-life analysis for Transformers

Transformer replacement programs are driven by prioritizing transformers according to their condition and their contribution to network reliability. Transformers in the most critical locations that are in the worst condition are the first to get replaced. Ideally, a transformer is replaced at the moment before it reaches its end-of-life.
