NEMA Low Voltage Surge Protective Devices Section Unveils Updated Website

NEMA Low Voltage Surge Protective Devices Section Unveils Updated Website

The NEMA Low Voltage Surge Protective Devices Section (5VS) recently unveiled a major update to its to its NEMA Surge Protection Institute website, nemasurge.com.  It is an educational effort to heighten awareness of the benefits of surge protection, and to promote its proper application and usage.  Nemasurge.com was reorganized with a new look, and some of the content was updated to reflect changes in the industry and standards.  This effort was led by the 5VS Industrial Development Read more [...]
Government Funding for Energy Efficiency Programs Goes Unspent

Government Funding for Energy Efficiency Programs Goes Unspent

An Energy Department audit found that nearly $900M for efficiency grants to states, cities has gone unspent.  This money was authorized in the 2009 economic stimulus law to help states, territories, local governments and Indian tribes improve their energy efficiency and reduce fossil fuel emissions, through projects such as retrofitting buildings.  These grants are an important way to improve the efficiency of older buildings, reduce waste and create jobs.  NEMA members manufacture Read more [...]
Bridging Solar Power And Wind Power

Bridging Solar Power And Wind Power

I was listening to the Wall Street Journal this Morning and came across an interesting story.  Two Italian designers came up with way to make wind turbines less of a potential eyesore.  They have designed a proposed highway bridge that incorporates wind turbines between the support pillars. Additionally, the road would be paved with solar cells and covered with a hard plastic.  The innovative design would generate as much as 36 million kWh per year, which is enough electricity to power Read more [...]
Leviton response to EVSE Cord and Plug Controversy

Leviton response to EVSE Cord and Plug Controversy

In response to NEMA's eiXtra: January 11, 2011 Feature Article entitled EVSE Making Waves Across the Industries Leviton would like to clarify the comment that,  “There is some controversy surrounding the non-permanent EVSE installations right now, and whether or not they are allowable under code, but it appears that Ford is confident in Leviton's reading of the code.” Leviton Manufacturing’s Electric Vehicle Supply Equipment complies with applicable requirements Read more [...]
Trimming Trees Trims Power Troubles

Trimming Trees Trims Power Troubles

Utilities need to trim trees around overhead power lines to minimize power outages that may occur during powerful storms due to falling branches.  Many times a utility’s tree trimming program runs into opposition from a locality’s tree canopy preservation policy.  A town wants to preserve its tree canopy and residents will vociferously complain that a utility “butchered” the tree in of their home.  These same residents will also complain that their electrical Read more [...]
The Return of Manufacturing to the US

The Return of Manufacturing to the US

Is it possible that manufacturing may leave China and return to the US?  This may be wishful thinking, but there are signs that we may be moving down that path.  Consider the following from an AP article that appeared on many news outlets recently: Labor costs in China are increasing 15% per year since 2008.  Workers are demanding better wages and working conditions due to a labor contract law that made them more aware of their rights Tax preferences for Read more [...]
Fire Safety

Fire Safety

The Fire Marhal in Loudoun County, Virginia has seen a need for smoke alarm installation and maintenance in the County.  While the annual death rate of people from fires has fallen dramatically over the past 25 years, the percentage who died at home has remained high at approximately 75 - 80%.  The useage of smoke alarms increased during this time, but human indifference is thought to be a factor.  Smoke alarms tend to wear out after a decade and Read more [...]
The Importance of Surge Protection

The Importance of Surge Protection

Came across an article in the Washington Examiner this week.  An arc in an underground power line caused a surge that blew off an electric meter in the basement of an apartment building in Washington, DC, and caused a small electrical fire.  Fortunately no one was hurt, but 75 people were temporarily displaced.    This demonstrates that residences should be protected from surges to prevent costly damage.  The members Read more [...]
Globally Harmonized Standards Hits a Roadblock

Globally Harmonized Standards Hits a Roadblock

It's disappointing that US interests were rejected during the IEC TC14 Power Transformers meeting held in November.  Two IEEE standards were offered for consideration under the IEEE/IEC Dual Logo and/or Joint Development agreements, IEEE PC57.123 Guide for Transformer Loss Measurement and IEEE PC57.15 Standard Requirements, Terminology, and Test Code for Step-Voltage Regulators.  Phil Hopkinson, HVolt Inc., and Jin Sim, Waukesha Electric Systems, made good presentations on Read more [...]
You Can’t Get There From Here

You Can’t Get There From Here

Many people would agree that renewable energy is a good thing.  Getting electric utilities to rely less on coal and natural gas to fire plants would reduce one of the biggest sources of CO2 emissions in the US.  There is a problem with this strategy – transmission.  As reported recently in the Washington Times, San Diego Gas & Electric wants to build a large solar power operation in the SoCal desert, but the current plan calls for a 150 mile high voltage transmission line that Read more [...]
