Fluorescent Fiber Optic Monitoring: Key Technical Advantages
Q: Why choose fluorescent fiber sensors for high-voltage equipment?
- ±0.5°C accuracy on live 35kV switchgear contacts (IEC 62271-1 certified)
- 64-point real-time monitoring with 15kV galvanic isolation
- Direct winding embedding in 500MVA transformers (25kV/mm dielectric)
- EMI immunity under 150kV/μs transients
- Proven 99.97% uptime in 220kV substations
→ 40% maintenance cost reduction verified in operational case studies
