    May 21, 1999GasVue easily detected the leak and pinpointed its exact origin. A halogen detector could detect the leak in the control box, but much more time would be needed to determine the source of the SF6 at the breaker. At the Koeberg 400kV GIS, the GasVue camera accurately located a leak on a feeder link compartment.
