Locating technicians must go through several steps to do a locate or trace. First, they open up an enclosure to isolate each wire from ground. Then they remove each grounding harness, so they can listen to find the line. However, the process of reassembling creates the potential for new problems. Nuts can get lost, bonds become loose, or harnesses can end up unattached.

Meet Kevin Mabie, Northeast Territory Manager, as he discusses his communications industry outlook for the next five years - and how increased access to fiber bandwidth will help drive future growth to rural areas.
Electric utility operating system reliability is an important factor of utility performance. As a common practice, distribution arresters are assembled with a ground lead disconnector (GLD) designed to respond to arrester fault current during a short by detonation of a cartridge inside of the disconnector housing.

Four years, several prototypes and thousands of installations later, Hubbell has satisfied Alliant Energy’s need for a stronger neutral clevis.
Alliant Energy identified the need for a better neutral clevis more than a decade ago. Their distribution system has an under-hung neutral and some neutral conductors were attached to poles with vertically mounted clevises. In other words, the neutral was held to the side of the vertically-oriented, spool insulator by a steel tie wire.

Rising water can damage or weaken existing transmission line and substation utility foundations. In flooded areas, drilled shafts and driven piles need to be inspected to determine if damage has occurred as a result of erosion. Here’s what you need to check:
In Alaska, the 115-kV Quartz Creek transmission line connects two hydroelectric dams on the Kenai Peninsula with the ‘rail-belt’ — an area containing Alaska’s railroad, its most populous cities and about three-fourths of the state’s population. A ﬁfteen mile section of that line was rebuilt last November, in an area where snow storms regularly drop feet of snow throughout the winter.
The Versa-Tech® I and Versa-Tech® LT reclosers use a 2.4GHz remote radio to communicate over WiFi. Utilizing this option, there is no need for a local radio. The module is compatible with Versa-Tech I recloser running firmware versions 3.xx or 4.xx and with Versa-Tech LT recloser running firmware version 5.xx. The WiFi radio attaches in the same location as the Digi/XBee and SiFLEX radios and has the capability of communicating up to 100 feet from the recloser.
