British telecom regulator Ofcom has issued a report indicating that 2008 was a record year for enforcement actions and fines levied. Illegal broadcasting, or so-called pirate radio, continued to be a problem in heavily populated urban areas. During 2008 Ofcom carried out 36 studio raids, secured 28 prosecutions and 14 formal cautions, removed 489 illegal transmitters, and … [Read more...]
IEEE & NATO Sign TCA; Will Work on Human EM Exposure
The IEEE Standards Association (IEEE-SA) and the NATO Standardisation Agency (NSA) have signed a Technical Cooperation Agreement allowing these organizations to share knowledge of each other’s standards development activities and to avoid duplication of technical standards wherever possible. Under the terms of the TCA, IEEE-SA and the NSA will exchange information about ongoing … [Read more...]
EM Induction Sensors vs. Land Mines
Researchers at the Georgia Institute of Technology have created a test facility to evaluate sensors used for the detection of land mines. A unique automated system measures the response of individual electromagnetic induction sensors or arrays of sensors to land mines buried at many different angles. The sensors emit magnetic fields and then detect the response from the … [Read more...]
EMC Filters for Improved Solar Reliability
The FN 2200 range of filters from Schaffner reduces conducted emissions when used with photovoltaic solar energy inverters on the DC input side. Conducted emissions toward the solar panel are reduced along with the probability of EMI radiation from the solar panel, thus preventing premature panel aging caused by HF leakage currents. When used in conjunction with the … [Read more...]
Filtered Power Entry Modules Target General/Medical Applications
New 10-amp versions have been added to Tyco Electronics’ Corcom GG series general- purpose power entry modules and HG series for medical applications. The GG series of power entry modules combines the functions of a general-purpose RFI filter with an IEC power cord connector and single- or dual-metric fuse holder. The HG medical version features reduced line-to-ground … [Read more...]
Industry Standard Metalized EMI Filters Boost Appliance Safety
The new 095 Series of filters from LCR Electronics uses a highly cost-effective metalized film technology that provides both the high reliability and fail-safe characteristics often associated with more expensive older technologies such as impregnated paper-foil. If a failure occurs, the metallization over the film evaporates, eliminating the chance of electrodes of the … [Read more...]
Cost Optimized 3-Phase Line Filter
A line of 3-phase line filters from Schurter has been dubbed series FMAC ECO and FMBC ECO. These compact and cost optimized filters are in ECO designed and especially suited for use in drive systems, engineering installations and places where frequency inverters cause electromagnetic disturbances. The EMC filters are arranged for use with 480 VAC installations and are available … [Read more...]
