Power Quality and EMC in Smart Grid
Magnus Olofsson, President, Elforsk – Swedish Electrical Utilities’ R & D Company, Stockholm, Sweden The Smart Grid is increasingly seen as a means to facilitate climate friendly renewable energy sources (renewables), and as a way to enable efficient use of electricity. For example, modern electrical networks can link wind- and solar power with electric cars. A consequence … [Read more...]
Swiss Experimental Station on Lightning Research at Mount Säntis
Farhad Rachidi, Swiss Federal Institute of Technology (EPFL), Lausanne, Switzerland Marcos Rubinstein University of Applied Sciences of Western Switzerland (HEIG-VD), Yverdon-Les-Bains, Switzerland The problem of lightning electromagnetic disturbances has been undergoing thorough reconsideration for the past few years due to the increasing complexity of electrical power and … [Read more...]
Electromagnetic Interference in the Data Center: To Shield Or Not To Shield
Jordi Ferri, Shielding, Power & Cooling Division Manager, Advanced Shielding Technologies Europe S.L. (AST), Barcelona, Spain INTRODUCTION When designing a data center, many things need to be taken in account. One of them is availability and downtime depending on desired Tier configuration (see Table 1). For Tier III and Tier IV data centers, apart from redundancy of the … [Read more...]
Multi-tone Testing Can Save Both Time and Money
Jason Smith, Manager Applications Engineering; Pat Malloy, Sr., Application Engineer; AR/RF Microwave Instrumentation, Souderton, Pennsylvania, USA Given the huge amount of time required to conduct a radiated immunity test, it is no wonder operators “dream” of ways to improve efficiency to speed up the test. The musings generally go as follows: Can one antenna cover the … [Read more...]
An Integrated Development Environment for Modeling the Radiated Electromagnetic Emissions
ABHISHEK RAMANUJAN, ZOUHEIR RIAH, ANNE LOUIS, Research Institute for Embedded Electronic Systems, Saint Etienne du Rouvray, France A cutting-edge electromagnetic emission modeling tool has been presented in this paper. With most of the existing electromagnetic compatibility (EMC) analysis tools, either demanding large computational resources or being available only for expert … [Read more...]
EMC Testing above 1 GHz: The Deadline Looms
When first mandated in the 1990s, the stated objective of the EU’s Directive governing EMC was, in broad terms, that commercial and domestic equipment, and certain industrial systems, should neither cause interference or be susceptible to interference. They should not emit radiated or conducted energy at RF frequencies and they should be immune to such emissions, within … [Read more...]
