Another option are certain fluorinated gas mixtures that also have less greenhouse gas potential than SF 6 . For example, the Zurich based energy supplier EWZ has been using such a solution since 2015, and in 2019 a 380 kV plant was erected in Bavaria, Germany. However, these gas mixtures lose their effectiveness at very low temperatures.

The Modular Switchgear Monitoring (MSM) is an add on system to supervise SF6 density in enclosures of high voltage gas insulated switchyards. It operates independently of existing control and protection devices. Highly stable SF 6 density sensors are used to continuously monitor the integrity of the gas compartments and identify gas losses at an early stage.
