Lightning Discoveries & Technologies

How this phenomenon affects electric utilities BY JIM SIEBERT, FOX 26 Chief Meteorologist Advances in technology are helping scientists understand lightning in ways that were not possible a few years ago. Beforehand, meteorologists primarily studied lightning, focusing most of their efforts on...

Distributed Energy Resources - Small Scale Power

Distributed energy resources (DERs) can benefit the power system and individual homes and businesses. DERs can increase the resiliency and reliability of the power grid, reduce greenhouse gas emissions, reduce the overall power cost, and provide power at the point of use. Several types of DERs can...

High Voltage AC Transmission Lines

Three-phase electric power systems are used for high and extra-high voltage AC transmission lines (50kV and above). The pylons must therefore be designed to carry three (or multiples of three) conductors. The towers are usually steel lattices or trusses (wooden structures are used in Germany in exceptional cases) and the insulators are generally glass discs assembled in strings whose length is dependent on the line voltage and environmental conditions. One or two earth conductors (alternative...
