Re: [RE-wrenches] utility line voltage issues

[Marv Dargatz]

Check out the following link.  Just ONE example of what the utility must deal with. http://tdworld.com/customer_service/power_new_technology_solves/ I'm not defending the utilities.  They definitely have their faults (argh, argh), but they have some severe challenges that we are not always sensitive to. See Ya!
