Precision Fiber Optic Temperature Sensor Systems for Transformer Hot Spot Monitoring
FJINNO provides the industry's most reliable fiber optic temperature measurement technology, engineered to prevent catastrophic failures, extend asset life, and enable the era of smart monitoring transformers.
Discover Our SolutionWhy Direct Winding Temperature Monitoring is Critical
Insulation degradation is the primary cause of transformer failure, and it accelerates exponentially with temperature. Traditional methods that estimate winding temperature are often inaccurate and slow. A single undetected hot transformer event can lead to irreversible damage.
- Move beyond inaccurate estimations from a resistance thermometer or oil temperature thermometer.
- Achieve true condition monitoring of transformer assets for maximum reliability.
- Enable predictive maintenance strategies and achieve the "doble life of a transformer 2025".
FJINNO: The Best Solution for Transformer Safety
Our transformer monitoring system utilizes advanced fluorescence sensor technology. The sensor fiber optik is completely immune to high voltage and electromagnetic interference, allowing for direct installation on the windings—the only way to get a true transformer winding temperature reading.
- Precise, real-time transformer hot spot monitoring.
- A robust transformer alarm system against thermal overload.
- The ultimate transformer winding temperature indicator and control tool.
