Power transformers are one of the most important components of electric #networks. These devices are very expensive, and as a result diagnosis and temperature #monitoring of these systems is imperative to ensure safe operation. Fiber-optic temperature #sensors for direct winding #temperature measurement in #transformers offer an excellent and increasingly cost-effective solution for direct, accurate, and real-time hot spot temperature measurement. TSENS and T301 by RUGGED MONITORING are the most durable solutions for transformer winding hot spot monitoring due to their high accuracy and reversibility.
