The company that I work for has developed an instrument that monitors low voltage (120/240) power lines that are "t-tapped." The only residential neigborhoods that use this type of technology (or lack thereof) is overseas (that we know of.) We have been traveling to the UK to test our equipment. In a typical neighborhood they have one transformer with 4 or 5 3-phase cables running down different areas. Each house is then tapped off of the main line and then buried underground. Obviously not the best way to run electrical but hey, if gives us something to do. We are obviously looking for a place in the states that is set up like this. We have recently found out that some places in South America also distribute power this way. Any information that you know would be appreciated! Thanks
