Tech Notes from the Field

When given the time I will click through my Links column and see what may be new or of interest.  Also, to check and see if they are still valid.  This morning I ran across EEP, Electrical Engineering Portal, as they always have something interesting power related.  We all need and use power.  Without power we have nothing to do.  Today’s feature article is 5 Types of Equipment Which Generates the Most Harmonics.  Head on over and get a refresher on what they find.  We all know most of these and how they interfere with RF, especially AM radio.

What is very nice about this article is it doesn’t just brush by the topic.  There is some good detail in there.  For example I was able to refresh my understanding between on-line, off-line, and line-interactive UPS’s.  It may be obvious, but a little refresher keeps them brain cells up to date.  All in all, a good read.
