Portable gaz sf6 Gas Testing Instrument Excites the Industry

To guide users in considering such testing, measurement of humidity in Sulfr hexafluoride gas is seen as a preventive medicine approach to substation maintenance. If the humidity content is low, then the possibility of HF and SO2 creation is very low. If the humidity is high, then those by-products will be created in high enough concentrations to corrode the insulators and result in unwanted arc-over (short-circuiting) in the equipment. Here are a couple of sources of unbiased humidity discussion…Get price

Drying and particle filters absorb moisture, gas and dust

On the suspicion that SF 6 gas in a circuit breaker is contaminated or humid, we strongly recommend the use of drying and particle filters between switchgear and service cart. Moisture and both gaseous and dusty decomposition products as well as oil aerosols are adsorbed by special drying and particle filters during the recovery operation. Thus, service carts are protected effectively against contamination as most of the moisture and decomposition products are collected by the prefilter units.Get price
