Measurement of air flow between the floors of houses using a

Apr 24, 1988 · A simple measuring technique is described in which two portable gaz sf6 systems were employed. A comparison of air flow patterns in a super- insulated house and a standard house is made. The method has been also validated in the laboratory by measuring air flows between two small chambers using both the tracer sys- tems and an independent flow device.Get price

Trafag gaz sf6 Air Sensor leak testing for transformers

Trafag sf6 gas Air Sensor leak testing for transformersObviously, for the GIS operator, it is useful to detect SF 6 leaking into the oil tank as a first step toward localizing and repairing the leak. Also, SF 6 in the oil can complicate the Dissolved Gas Analysis (DGA) processes that are so important to transformer health assessment and maintenanceGet price

Compressor unit for insulating gas measuring devices

As the device is leak-tested there are no SF 6 emissions. The oilfree compression avoids the SF 6 test gas from being contaminated with oil mist. Any contamination of the measuring gas e. g. caused by traces of moisture can therefore be excluded. The small compressor is almost maintenance-free and easy to handle.Get price

Measurement of electron transport and effective ionization in

Feb 03, 2006 · From the measurement of v e and ND L we were able to calculate the ratio between the electron mobility and the longitudinal diffusion coefficient D L /K e, which are shown plotted in figures 5 and 6 for the SF 6 –air and SF 6 –O 2 mixtures. Again, we observe a slight dependence of this ratio on the SF 6 content.Get price
