How to predict or early detect SF6 leaks in ISA's electrical infrastructure, in indoor and outdoor installations?

SF6 gas is colorless and odorless, and is also widely used in the electrical sector due to its electrical insulating and arc-extinguishing capabilities, which makes it a key component in the design of switchgear and self-contained substations that take up less space. However, SF6 is a greenhouse gas with a high GWP (Global Warming Potential). The current SF6 monitoring process in ISA is carried out by measuring pressure in the gas containers; this method does not allow for early detection since it sends alarms once a considerable amount of gas has been lost. This situation, exacerbated by the increase in the use of SF6, contributes significantly to the environmental impact, despite efforts to keep leakage below 0.5% per year. ISA has implemented indirect detection actions for SF6 loss with the measurement of gas density in the chambers, however, there are many more operational variables involved, which complicates the ability to predict or detect SF6 leaks early and accurately, negatively impacting the fulfillment of ISA's CO2 emissions reduction targets.


This solution should ensure effective compliance with the strategic CO2 emission reduction targets and minimize the impact of said gas through the use of innovative technologies for constant, intelligent, effective and low-cost monitoring.
