Sergi

SERGI is an engineering company specialized in protecting critical power transformers against rare, high-impact failure scenarios. We operate where the consequences of transformer failure extend beyond the asset itself — impacting human safety, grid resilience, environmental protection, and business continuity. SERGI does not provide generic equipment or promise protection levels that cannot be demonstrated. Our role is to engineer defensible protection architectures, grounded in physical failure mechanisms, independent validation, and real operating conditions. Our approach supports infrastructure operators, insurers, and authorities in making technically defensible decisions when prevention alone is not possible and mitigation must be engineered within milliseconds. With over 70 years of field experience and international deployments across utilities, industry, and critical infrastructure, SERGI contributes to long-term infrastructure resilience through engineering judgment — not marketing claims.
