Across the African continent, power utilities face unique challenges in maintaining critical transformer assets. From harsh environmental conditions to rapidly growing demand and limited maintenance resources, the need for reliable transformer monitoring systems has never been more crucial. FJINNO is proud to offer advanced fiber optic transformer monitoring solutions specifically designed to address the unique challenges of African power networks.
What is Fiber Optic Transformer Monitoring?
In today’s utility industry, there are three common methods for transformer winding Temperaturmessung: simulated, calculated, and direct measurement via fiber optics. Among these, only Faseroptische Abtastung systems provide true direct measurement of winding hot spot temperatures, delivering extremely accurate readings when it matters most.
FJINNO’s fiber optic transformer monitoring technology utilizes advanced fluorescing-tipped probes manufactured with proprietary rare-earth materials. Our monitoring systems provide a pulse of light that excites the rare-earth coating where the decay rate functions as a precise temperature indicator. This allows for temperature measurement within ±0.2°C using our enhanced blue LED phosphor technology – significantly more accurate than conventional GaAs-based systems that typically only achieve ±2°C accuracy.
Unlike some competing technologies that rely on white light sources requiring frequent maintenance, FJINNO’s systems use long-life LED technology that ensures reliable operation for 15+ years even in challenging African environmental conditions.
