  • How to pinpoint SF6 leaks quickly without the need to de

    May 21, 1999A 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. While the station staff was aware that the compartment was leaking, GasVue pinpointed the location.
