ge SF6 Air Sensor testing for gas measurement

A vacuum purge cycle and gas storage system ensures that no air can contaminate the gas sample and that no SF 6 gas is able to escape during the testing period. SF 6 gas pressure in the internal sample compartment is recorded and logged by the analyzer. All measured gases are analyzed and data logged simultaneously with only a few minutes required to achieve a stable reading.

  • SF6 Monitoring System for GIS – GE Grid Solutions

    B Watch. SF 6 Monitoring System for GIS. With worldwide scrutiny on SF 6 gas usage, increased environmental reporting requirements and even possible penalties, precise early detection of small gas leaks in Gas Insulated Substations that use so much SF 6 is essential. The B Watch uses the latest generation of EMC resistant digital gas sensors to continuously measure gas pressure and temperatures in order to track changes in density and detect gas leaks down to 0.1% per year.
