Underground Distribution Sensors

Exploring the benefits of wide-area monitoring BY TED MYERS, On-Ramp Wireless The average citizen and business experiences over 120 minutes of electricity outage duration a year. This has a significant societal impact costing 10s to hundreds of billions of dollars annually. Furthermore, the measure...

Copper Theft: A Call to Action

How utilities can stand firm to save money and save lives BY PHILL FELTHAM, Executive EditorElectricity Today Magazine Copper theft has become a growing problem for utilities in Canada and the United States. This precious metal has increased in value in recent years, so thieves are stripping...

Monitoring Underground Lines with SCADA

How SCADA can help prevent repairs and service disruptions BY RICHARD CLARK, InduSoft Underground transmission and distribution lines create unique challenges, as they require special insulation materials to protect conductors, and complex cooling systems because heat cannot be dissipated in free...

ACSR and ACCC

The Evolution / Revolution of Overhead Conductors... and why it matters

Brief Background:

In the early 1900’s Aluminum Conductor Steel Reinforced (ACSR) conductor was developed to replace copper wires, due to the war effort when copper was needed for munitions. In the 1970’s growing demand for electricity inspired the development of higher capacity Aluminum Conductor Steel Reinforced (ACSS) conductor. The ACSS conductor became known as the first “High-Temperature, Low-Sag” (HTLS) conductor. The design used the same steel core as ACSR (with improved galvanized coatings) and fully...
