SF6 Leak Detection Methods for GIS Equipment
For SF6 gas leakage rate detection in GIS equipment, when using the quantitative leak detection method, the initial SF6 gas content in the GIS equipment must be accurately measured. According to relevant standards, the measurement error should be controlled within ±0.5%. The leakage rate is calculated based on changes in gas content after a period of time, thereby evaluating the sealing performance of the equipment.In qualitative leak detection methods, direct visual inspection is commonly used,
