Patent number: 9210257Abstract: Methods of testing at least a transmission line of interest within a group of transmission lines for anomalies using Time Domain Reflectometry are provided. The testing methods set forth herein aim to improve, for example, the quality and accuracy of information collected when propagating signals along a length of transmission line in order to pinpoint specific anomalies. To achieve this and other benefits, the testing methods simultaneously impose, for example, pulses of equal magnitude and form onto a group of transmission lines, such as the phases cables of a three phase power transmission cable system. From this, at least one transmission line from the group is monitored for reflected signals caused by impedance change. An example TDR is also provided.Type: GrantFiled: June 9, 2011Date of Patent: December 8, 2015Assignee: UTILX CorporationInventors: Nelson Hall, Keith Lanan, Oscar E. Morel

Publication number: 20060169475Abstract: A connector for repairing and connecting at least one section of a first electrical cable having an outer surface, an interior end, an exterior end, and a central conductor portion. The connector includes a sleeve having first and second open ends, and a hollow interior to permit the passage of fluid therethrough. The connector also includes a port providing fluid communication with the hollow interior of the sleeve and into the central conductor portion of the first electrical cable. The sleeve is capable of receiving and forming a fluid-tight seal with the interior end of the first electrical cable.Type: ApplicationFiled: August 2, 2005Publication date: August 3, 2006Applicant: UTILX CorporationInventors: Glen Bertini, Bernd Grave, Keith Lanan, Albert Chau, William Stagi

Publication number: 20050006117Abstract: A flow-through cable for transmitting information (20) is provided. The cable includes a jacket (22) having a length and an information conducting core (26) coaxially received within the jacket. A first insulation layer (24) surrounds the information-conducting core and has a dielectric strength. The cable further includes a first conduit (28) disposed within the jacket. The first conduit is adapted to permit a compound to flow therethrough and is chemically permeable to permit at least a portion of the compound to diffuse through the first conduit.Type: ApplicationFiled: May 10, 2004Publication date: January 13, 2005Applicant: Utilx CorporationInventors: Glen Bertini, Kim Jenkins, Keith Lanan, Glenn Jessen

Patent number: 6489554Abstract: A method and apparatus for connecting flow-through cables. Flow-through cables have a conduit or a plurality of conduits longitudinally placed inside the cable to allow fluid passage. Special terminators, joints, and methods for installing these devices are described herein. One method for connecting two flow-through cables involves: inserting a tubing material into the conduit of one flow-through cable, placing a crimp connector over the cable's conductive core and crimping the crimp connector. The tubing material is then placed into the conduit of the second flow-through cable, the cables are aligned, and then the crimp connector is fastened to the conductive core of the second flow-through cable.Type: GrantFiled: October 11, 2000Date of Patent: December 3, 2002Assignee: Utilx CorporationInventors: Glen J.

Patent number: 5907128Abstract: A device for repairing and electrically connecting at least two sections of electrical cable includes an elongate connector, for example a tube, having two open ends that are each adapted to receive an end of an electrical cable section. The cable connector has an interior wall longitudinally dividing the cable connector into two portions, each portion having a hollow interior for containing the end of one of the two electrical cable sections. The cable connector also has an orifice in each of the two portions communicating with the hollow interior of that portion. A closure device, such as a threaded plug, is mateable with each orifice.Type: GrantFiled: February 13, 1997Date of Patent: May 25, 1999Assignee: Utilx CorporationInventors: Keith Lanan, Albert W.
