  • Partnerships target SF6 emissions - POWERGrid International

    Oct 01, 2000They are accomplishing this in many ways. Some have invested in recycling carts and SF6 management training. Others are replacing older, leakier circuit breakers with newer, tighter ones. Still others are using leak detection methods (e.g., laser systems and halogen sniffers) to detect where leaks are so that remedial action can be taken.
