Shelf Life of Calibration Gas - Weatherall Equipment

Reactive gas mixtures typically have a shelf life of one year or less. After shelf life has expired, it is likely that the concentration of the reactive gas will either decrease or eventually disappear all together. Non-reactive Gas Mixtures. Non-reactive gas mixtures are calibration gas mixtures that do not include any reactive gases. This is

Using nitrogen(N2) or dry air to replace SF6 as insulation media in high voltage apparatus is a hot topic in the development of environmental friendly switching equipment. To ensure compact structure and small size of the devices, engineers need to study the insulation characteristics of the utilized gas and the solid-gas compound insulation.
