U.S. government announces new voluntary guidelines to address public concerns
BY PHILL FELTHAM, Editor-in-Chief
Electricity Today Magazine
Smart Grid equals innovation to many utilities and their customers, but not everyone shares that sentiment. In fact, many customers and media outlets perceive the Smart Grid as a way for utilities and third parties to invade their privacy (the negative publicity toward smart meters is one great example).
Luckily, governments in both Canada and the United States are listening and are actively introducing legislation for regulation on a variety of Smart Grid technologies. Twenty-one U.S. states are considering at least 61 enacted or pending bills to encourage innovation, to regulate emerging technologies, and to protect consumer interests and concerns. (more…)
Improving substation maintenance best practices for greater success
BY BUDO MILOVIC, DV-Power
Currently, substation maintenance—regular or emergency—operations and best practices must fit the utility’s goal of accomplishing more with less, in order to maximize assets and minimize outages. A caveat to this weighty goal is to accomplish more with less with a reduced workforce and under tight budgets. Field workers face this reality daily. Therefore, to overcome such challenges, maintenance crews have to be properly equipped and trained for these everyday demanding tasks. (more…)
Weighing choices from AMI to Zigbee to Wi-Fi and cellular
BY HOWARD NG, Comverge
The demand response industry is currently experiencing some of its greatest success currently in the marketplace. However, similar to all technologies that stand the test of time, demand response started somewhere different from where the technology is now. The communication protocols available for demand response participants and their respective utilities, in particular, have evolved significantly. (more…)

How to prevent failure with partial discharge testing
BY HENNING OETJEN, Megger
Partial discharge (PD) measurements are increasingly used as a reliable and non-destructive diagnostic method to detect weak spots in the insulation of underground cables. Routinely, partial discharge measurements are utilized in laboratories for testing cable reels prior to commissioning and in the field to verify installation quality. (more…)
Debunking the myths surrounding aluminum usage
BY SCOTT MAY, VIJAI NARAYANAN, ANDREW LAWLESS, Siemens
Much has been written about the use of aluminum versus copper for transformer conductors within the electrical industry. Aluminum conductors have been used successfully in the electrical industry for more than 100 years; unfortunately, misconceptions about their applications still exist. In Europe, aluminum has been used as the standard material for cast-resin transformer windings for many decades. (more…)
New regulation removes “optional” to increase worker safety
BY CRAIG FIRL, Capital Safety
The U.S. Occupational Safety and Health Administration (OSHA) published updated rules and regulations in April 2014 that impact fall protection for the electrical utility industry. These new regulations, which replace rules dating back to the 1970s, have been in development since 2005 and will replace guidelines that were both out-of-date and inconsistent. OSHA estimates the new rules will prevent an additional 118 workplace injuries and 20 fatalities each year. (more…)
