Advanced Diagnostics and Failure Prevention in Power Transformers: Dual Case Study Investigations of Magnetic Flux Leakage and Cellulose Insulation Degradation at Samra Electric Power Company (SEPCO), Jordan

Ensuring the reliability and longevity of power transformers requires accurate fault diagnostics and targeted maintenance strategies. Conventional diagnostic approaches often fail to detect early-stage faults effectively, necessitating a transition toward condition-based monitoring and data-driven analysis. This study presents a comprehensive diagnostic investigation of two generator step-up transformer failures at Samra Electric Power Company, Jordan, a multi-stage diagnostic framework was implemented to systematically investigate transformer failure case histories. Traditional diagnostic methods, including electrical measurements, chemical analysis, and mechanical inspection were applied to identify underlying failure mechanisms and guide structured testing and troubleshooting…
