Turn Measurement Reality into Action
Since the introduction of gas insulated equipment (GIE), mechanical gas density monitors have been used worldwide. In line with IEC 62271-203 and IEC 62271-1, they help ensure that gas pressure and gas density inside GIE compartments stay within the required limits to maintain dielectric strength. Using temperature-compensated mechanical systems, they also provide basic leakage detection and can trigger safety-related functions such as interlocks.
Today, millions of these devices are installed globally. And despite their high reliability, monitoring is still often manual: on-site readings, inconsistent documentation, and a lack of trend data remain common. This manual, fragmented, low-resolution approach represents the Measurement Reality in many conventional GIE systems.
Utilities rarely start with fully digital, always-on sensing in GIS. They start hybrid — reactive offline readings, periodic sampling, and partially analog data. That data is still operationally relevant. The challenge is making it consistent, explainable, and decision-ready.
