The trial for non-contact means of pin-pointing SF6 leaks makes use of FLIR infrared gas detection cameras which are capable of visually detecting SF6 gas from a distance and showing it on a display as a dark smoke plume. After each pin-pointing exercise, a non-invasive method of reducing the leak is tried through encapsulation of the switchgear component with Oxifree TM198 resin, a new product which is currently utilised mainly for corrosion protection. This methodology is expected to be more cost effective than current practice and to result in significant environmental benefits.
Reduction of SF6 emissions from switchgear will reduce the environmental impact of power systems.
