German Superconducting Cable Ups Power with Low Transmission Loss
The world’s longest superconducting cable has been integrated into the power grid of a city in Germany, marking the start of a landmark practical test with the potential to save billions of dollars in power industry costs around the world. “This is a good day for . . . the transformation of the energy system in Germany. Today, we start the first practical test of … [Read more...]
New Magnetic Material Could Boost Hard Drives, Protect Electrical Grids
Scientists at the University of California, San Diego have developed a highly sensitive magnetic material they say could drastically change computer hard drives and electrical grids. Made of thin layers of nickel and vanadium oxide, the material is extremely responsive to heat and requires only a small shift in temperature to alter its magnetic properties. "We can control the … [Read more...]
Power Lines to Help Map Space Weather
A one-to-two-year pilot project scheduled for launch later this year will utilize U.S. high-voltage power lines as a means to better understand solar events that threaten the electric grid. Led by heliophysicist Antti Pulkkinen of NASA's Goddard Space Flight Center in Greenbelt, Md., the research team will use scientific substations installed under high-voltage power … [Read more...]
Power Line Carriers Offer RF Interference Immunity to Utility Substations
AMETEK Power Instruments is offering two power line carrier products that address the growing concern of RF interference caused by the use of 3G/4G "smart" phones and routers in substation environments. According to the company, the new TC-10B/TCF-10B and Universal Power Line Carrier (UPLC) products are protected against changes in performance beyond specified tolerance, … [Read more...]

The International Electrotechnical Commission (IEC) has published IEC 61558-2-10 ed1., "Safety of Transformers, Reactors, Power Supply Units and Combinations Thereof - Part 2-10: Particular Requirements and Tests for Separating Transformers with High Insulation Level and Separating Transformers with Outpit Voltages Exceeding 1,000V." The standard is available in the IEC’s … [Read more...]
Using Lightning to Test Power Grid Health
A Swedish researcher has developed a new method of employing lightning and other high voltage currents to benefit power companies. Normally considered disruptive to transmission lines and destructive to the power grid, these so-called natural transients could be used instead to monitor the wear and tear on power components. “We can use these high voltages to obtain more … [Read more...]
MIT Study Sparks White Sands-SunZia Interference Debate
A new Massachusetts Institute of Technology study on the potential impacts of the proposed SunZia transmission line on White Sands Missile Range validates concerns regarding the project, a U.S. state lawmaker said earlier this week. Speaking to reporters during a telephone conference call on Tuesday, U.S. Congressman Steve Pearce of New Mexico said the study, which has not … [Read more...]
Earth Ground Testers Verify Reliable Grounding of Electrical Equipment
Test and measurement equipment provider Fluke Corporation has released the 1623-2 and 1625-2 earth ground testers for verification of a reliable connection to earth for grounded electrical systems. The new 1623-2 and 1625-2 earth ground testers are designed to assist engineers and electricians in meeting electrical codes, engineering standards, and local regulations to ensure … [Read more...]
