Power Transmission & Distribution (SF6) Instrumentation Solutions
High-voltage transmission and distribution equipment requires dependable monitoring of SF6 and alternative insulating gases to maintain dielectric performance, detect leakage and support environmental compliance.
Key Application Areas
- Gas-insulated switchgear (GIS)
- Circuit breakers and high-voltage substations
- Gas filling and recovery systems
- Density and leakage monitoring
- Laboratory gas analysis and service
Critical Measurement Points and Recommended Instruments
| Measurement | Recommended Instrument Types | Typical Locations |
|---|---|---|
| Gas density | Mechanical and electronic density monitors | Continuous condition monitoring of gas compartments |
| Pressure | Pressure gauges and transmitters | Filling, recovery and service equipment |
| Temperature compensation | Temperature-compensated density measurement | Stable indication over changing ambient temperature |
| Analysis | Portable gas-quality and leak-detection equipment | Moisture, decomposition products and leak checks |
Engineering and Selection Priorities
- Leak-tight connections and low emission handling
- Compensation for ambient-temperature variation
- Alarm contacts and remote monitoring
- Compliance documentation and calibration
