Dielectric fluid, nitrogen and SF-6 gas leaks have plagued the electric industry for years. In the past, it was common practice to take leaking equipment out of service, drain the oil, re-gasket all potential leak points, re-fill the unit and hope that the problems were corrected. In some cases a leak would re-occur and the whole process was then repeated. Today these leaks can be repaired without draining or de-pressurizing the equipment by means of hydraulically injecting compatible sealants to stop the leak. Colt Atlantic Services, Inc. has been providing on-line leak sealing services to a wide range of industries for over twenty years. Their Power Services Division has a highly experienced staff that is dedicated to repairing oil and gas leaks on electrical equipment.
