How would you measure the quality of SF6 gas (percentage and moisture)?

Herb Rogers, Head of High-voltage Service

ABB's answer

The quality of the SF6 gas can be tested using chemical and physical measurements stated by the IEC Recommendation. Generally, these measurements require sampling and laboratory instruments that guarantee a high accuracy in the measurement. If the humidity rate is higher than 300 ppm/vol at 20°C, the result will be considered UNSATISFACTORY.
