Increasing the observability and control of the transmission network
BY FRANK KREIKEBAUM, JERRY MELCHER, & JULIE COUILLARD, Smart Wire Grid, Inc.
The North American power grid has evolved into a connected set of four major interconnections delivering low-cost and reliable energy. The U.S. Energy Information Administration reports that the real price of electricity has dropped by a factor of 45 over the last 120 years in the United States. Meanwhile, a study published by the...
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...
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...
Based in Brighton, CO, United Power Inc. is the 2nd largest electric cooperative in Colorado.

A section of the United Power service area also heads...
Sediver has established in the USA an assembly factory for glass insulators in 2017 but also, and perhaps more interesting for some engineers, a laboratory capable of performing all the tests required by the world’s standards. Large test campaigns have already been conducted in this...

Insulators under fire, what are we talking about? A line directly in the fire is considered as lost A line near the heat of a fire can be saved What is the condition of insulators on a line nearby a fire? Reliability of insulators during or after a fire is a key consideration for T&D...

Reflections: Nearly twenty years ago when I got into the energy business, reliability was a second-tier design objective for most transmission engineers. Safety factors had already been established and the materials we used for structures and powerline wires (conductors) were well known. While...
