FAQs
What is the primary purpose of the SF6 Comprehensive Tester?
A: It helps detect moisture and impurities in SF6 gas, preventing equipment failure by testing humidity, purity, and decomposition products.
How often should equipment be tested with this device?
A: It’s recommended every 24 months, but critical or faulty units may need testing every 14 days. Keep purity above 97-98% and SO₂ below 10-12 ppm.
What are the key technical advantages of this “three-in-one” design?
A: It reduces gas waste and maintenance time by combining three tests into one device, minimizing leaks and improving efficiency.
What maintenance does the tester require?
A: Annual calibration is required for accuracy, with modular sensors that can be replaced on-site to reduce downtime.
What should I prioritize for optimal performance when using the SF6 tester?
A: Always ensure zero-leak connections by using the dedicated self-sealing joints. Tighten hoses properly to avoid introducing ambient moisture, which can cause false humidity readings.
How should I control the environment during testing?
A: Test in environments free from smoke or heavy dust, as these can interfere with the electrochemical sensors and affect accuracy.
How can I analyze data during testing?
A: Use the “curve display” feature to monitor real-time stabilization. If measurements fluctuate, it’s likely due to a poor seal or contaminated sampling line, not an issue with the gas.
What safety precautions should I take when testing for decomposition products like SO₂?
A: Always wear proper PPE, as decomposition products like SO₂ are toxic and corrosive, especially to the respiratory system.
