OFIL Systems / Satir
Gas Detection Cameras
Green Watt supplies advanced optical cameras for two critical but invisible electrical hazards: SF6 gas leaks in gas-insulated switchgear and circuit breakers, and corona discharge on overhead lines and high-voltage equipment. Cameras sourced from OFIL Systems (UV corona) and Satir (thermal/gas OGI) allow operators to locate leaks and discharge activity quickly and safely without taking equipment out of service.
Key Features
- Infrared OGI camera makes SF6 leaks visible as a dark smoke-like image
- OFIL DayCor® solar-blind UV cameras — fully operational in daylight
- No equipment shutdown required for SF6 leak surveys
- UV corona quantification via photon count display
- Simultaneous UV + visible-light fusion image display
- Zoom lenses for inspection of transmission towers from ground level
- GPS-tagged video and image data logging
- Also detects hydrocarbon gases, CO₂, and refrigerant gases (OGI models)
Applications
- ›GIS substation SF6 leak surveys
- ›Ring main unit (RMU) and SF6 CB leak detection
- ›Transmission line corona survey (insulators, conductors, fittings)
- ›Cable sealing end and surge arrester corona inspection
- ›Environmental compliance monitoring of SF6-insulated equipment
