RTU and HMI Redundancy in Electrical Substations

As the substation RTU takes on more applications, such as Human-Machine-Interface (HMI), alarm annunciation, math & logic and “relay communication processing”, its need for high availability increases. Anything that takes the RTU out of service – configuration change, firmware update, or...

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...

Aging Infrastructure and Grid Modernization

Asset and risk management for electric utilities BY SIRI VARADAN, UISOL, & SERGE VANASSE, Clevest Aging transmission and distribution (T&D) infrastructure is a critical issue for electric utilities, resulting in the need for utilities to make decisions regarding the replacement, repair, or...

Why technologies are important to grid modernization

BY MANI VADARI, Modern Grid Solutions

Electricity is one of the cornerstones of our economy. A modern electric grid is critical for our economic and national security. The National Academy of Engineering has called the North American power grid the “supreme engineering achievement of the 20th century”. Today’s power grid was designed to deal with a power delivery paradigm that we are slowly moving away from. The...

How to improve situational awareness of grid operations BY MARK FEDERLE, QinetiQ North America The adoption of Smart Grid technology in recent years has accelerated the modernization of the electric utility grid. This is a positive development given that the grid infrastructure in North America is,...

The Future of DC Transmission

An inside look at the rise of HVDC technologies BY DIETMAR RETZMANN & KARL UECKER, Siemens Energy The answer to the dreaded cry from towns and neighborhoods against building substations close by may be as simple as a four letter word (or acronym)—HVDC. Short for high-voltage direct current,...


Overhead T&D, Direct Current Technology

Direct current (DC) is the preferred technology for moving large amounts of power across long distances. DC results in overall higher efficiency and reliability than an equivalently-sized alternating current (AC) system moving the same amount of power. The Advantages of DC More efficient: Over long...

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...

Facing Wildfire? Choose Toughened Glass Insulators

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...

The Three R's: Reducing the Environmental Impact of SF6

Sulfur Hexafluoride (SF6) Gas is used as an electrical insulator and arc suppressant in high and medium voltage electrical equipment in the electrical power utility and industrial power industries. SF6 is also used in medical devices, metal production and other manufacturing applications. The same...
