RE: shielded data cables

J. Benary, You use shielded data cables when you don't pass EMC with unshielded data cables. There are no standards that say you must use them. However, there are many books, magazine articles, and various lectures on EMC that provide you design guidelines under what conditions shielded

Temperature Measuring of Magnetic Components

Hello EMC-PSTCers, I wonder if anyone knows of the method of measuring temperature limits on magnetic components. I happen to get involved in this and found that my results are different than the vendors result by as much as 10-15 degrees on measuring on a same magnetic component. Even

RE: Concrete as an insulator???

Don, In this instance we are operating in the range from 200-800 kHz; the output is used in a plasma process and so after ignition it will be from 800V to possibly 1500V depending on the chemistries. The concrete idea was going to be used for mounting purposes and also as a coil form. The

Per EN 60950 and UL 1950, Section 1.2.3. If it requires a tool to move it then it is considered fixed equipment. If the equipment has wheels and can be moved by the user without using tools then it is considered movable equipment. From your description below it sounds like you have fixed

EMC Testing of Equipment Built In-House

Doug, It sounds to me like this may be a good time to supply more information to the group. High power, 200 kW, at what frequency? Are we talking 13.56 MHz, 27.12 MHz, 40.68 MHz or are we discussing 18 GHz? Just thought that this may change the discussion a tad. --- Egon H. Varju

RE: Question on top 6 frequencies
