Reducing Wire-Down Incidents

It’s a fact, the frequency of downed power lines has been increasing, especially within the last few years as much of the equipment in many power grids enters the half century and older point. According to federal data, the U.S. electric grid loses power 285 percent more frequently than in 1984, when the data collection

The Best Method For Repairing Overhead Connectors

This video shows a typical scenario using infrared inspection of an overhead transmission line to identify a hot splice and then the proper correction of that hot splice using a ClampStar engineered mechanical shunt. ClampStar, along with proactive maintenance practices improves safety and prevents unplanned outages. ClampStar is the industry’s only PERMANENT solution for protecting

How To Find And Fix Failing Overhead Splices

ClampStar CSR-1631-048

PPL Utilities shows a shunt splice applied to an overhead line via helicopter, to repair a failing splice. Increasing power flows on some of the oldest lower-voltage circuits, especially during emergencies has put significant pressure on a power grid that was built mainly to serve local markets. ClampStar is necessary to help bring the power

Here’s What To Do After Finding Hot Connectors

As the grid continues to age, many utilities are increasing connector inspection frequency with a main goal of preventing outages and wire down incidents. One simple and relatively inexpensive line inspection method utilizes Infrared (IR) technology. The above images were provided by a utility located in Pennsylvania. Image #1 in the IR photo below shows

Many Utilities Ban The Use of Automatic Splices

There are estimated to be 250 million automatic splices installed on overhead power lines in North America. The majority of which were installed over 30 years ago. A variety of reports in the field indicate the service life of automatics is as short as five years up to, and perhaps surpassing 30 years. A recent

Choosing the Right Fastener – Part ll

By Carl Tamm In the first part of this article, a brief mention was made regarding “conductivity” of fasteners.  This second section will address that issue. Peculiarities of electrical connectors give rise to further thought of fasteners.  It is not exceptionally difficult, using reasonable workmanship and materials, to make an electrical connection of reasonable conductivity

Choosing the Right Fastener

By Waymon P. Goch With proper attention to the fastener assembly, the best choice is almost always fasteners of the same material as the components being joined. The primary reason is it eliminates differential thermal expansion and contraction, and just as important, since we are talking about electrical connectors, is that it will be conductive,

Fault Current and the Effects on ClampStar®

By Waymon Goch The terms fault and short circuit in electric power systems are frequently used interchangeably but there are slight differences. A fault can be defined as any abnormal flow of current whereas a short circuit is a current that completely bypasses the load by flowing directly to ground (earth) or by returning to

Corona, RIV/TVI Testing Complete

By Carl R. Tamm If your concept of corona is that it is commonly consumed with a slice of lime, you might wish to read a bit more about issues in our industry that differ slightly from that concept! Fair weather radio and television interference (RIV and TVI) generated by overhead lines are most frequently
