The Siemens range of gas-insulated switchgear (GIS), for rated voltages from 72.5 kV up to 550 kV, is an extremely successful product concept. Since its introduction back in 1968, Siemens has installed switch fields in all climatic zones of the earth, recording over 420,000 years of operation since.Images of Insulation GAS Filter Unit Siemens

According to the above table, we can see that 13 g of water has turned into tiny dew drops in a switchgear where the air temperature decreases from 30 ° C to 20 ° C. These dew drops are over switchgear sheets, insulators, cutters and other electrical equipment. Everybody in the industry knows how unpleasant this is.Hydrocarbon Dew Point | Gas Chromatograph - ABB

By reference to the table, the dew point is seen to be somewhere between 60 and 61 deg C (140-141.8 deg F). Prudence would dictate using the higher temperature as the operational dew point. Interscan is here to help you with all application and technical issues.[PDF]INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
