Bulletproofing the Grid

Bulletproofing the Grid

This piece was originally published in the September 2016 issue of electroindustry. Petter Fiskerud, Program Manager, Power Transformer Resiliency, ABB Inc. Recent events and developing threats remind us that as essential as the grid is to national and economic security—and our very way of life—it is and always has been vulnerable. The 2013 rifle attack on a California substation that damaged 17 transformers and six circuit breakers, causing 52,000 gallons of oil to be spilled Read more [...]
Why we like the new DOE transformer rule

Why we like the new DOE transformer rule

Recently the U.S. Department of Energy posted the Final Rule for the energy efficiency rulemaking for Distribution Transformers.  http://www1.eere.energy.gov/buildings/appliance_standards/product.aspx/productid/66  While some entities have criticized the Government’s final decision, the DOE Final Rule was largely on target.  DOE worked through huge amounts of data from all sides and came to a fairly good result. NEMA stuck to a few principles—backed up by data—throughout Read more [...]
Bipartisanship to Upgrade our Infrastructure?

Bipartisanship to Upgrade our Infrastructure?

This week, Senators Kerry, Warner, Hutchison, and Graham came together to announce their proposal to rebuild America’s infrastructure.  The Building and Upgrading Infrastructure for Long-Term Development (BUILD) Act, S. 652, would establish an American Infrastructure Financing Authority - a type of infrastructure bank that would provide loans and loan guarantees.  Transportation, Water, and Energy infrastructure projects greater than $100 million and of national or regional significance 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 [...]
Johns Hopkins Students develop device to protect workers from Arc flash

Johns Hopkins Students develop device to protect workers from Arc flash

Three students on an Engineering Design Project course at Johns Hopkins University undertook a challenge from the Baltimore Gas and Electric Company to develop a method to disconnect power lines from residential transformers at a safe distance, beyond the range of dangerous electrical arcs. Currently, utility workers must wear protective gear and use an 8-foot- long "hot stick" to disconnect lines that typically carry 7,600 volts. This operation sometimes triggers an explosive arc that Read more [...]
NEMA Premium Efficiency Transformers Program Gets an International Rollout

NEMA Premium Efficiency Transformers Program Gets an International Rollout

Yesterday morning at their annual meeting in Toronto, EEI Executive Director Diane Munns announced the creation of a joint program between EEI and NEMA to provide and procure efficient distribution transformers ahead of the Department of Energy's 2010 mandate. With CEOs from Consolidated Edison, TECO, Duke, and Pepco present, Munns lauded the efforts of utilities and manufacturers to implement efficiency technologies that are feasible today. Losses from transformers account for approximately Read more [...]
