As indicated this missive is --off topic-- I am looking for circuits (make or buy) that detect the presence of powerlines of the 50/60 Hz persuasion. These powerlines may or may not be loaded, so probably have to detect the e-field as opposed to an h-field. Any suggestions will be appreciated. Distance from powerline will vary from inches to several feet.
