Dear Editor:
My name is Philip A. Ley
I have been in the electrical and electrical engineering trades, started back in 1980 when I was in high school.
I graduated from Milwaukee Area Technical College in 1984. With a lot of continued education, I have worked with community and power companies on stray voltage and stray magnetic fields. I have been in the electrical field most of my life. I have made suggestions for electrical code changes specifically for stray voltages. Example, added four wire drops from transformers instead of three wire so that the grounding and neutrals are run on separate wires on center poles to farms. Other code changes were to have four wires to all electric ranges and dryers. Along with grounding of electric water heater correctly.
Another suggested code changes was for power companies to increase the size of grounding wires on powerlines and installing a grounding rod for each power pole instead of one every 5, 10, or 20 miles.
There is continuous 24-hour monitoring for stray voltages and loads with all the new code changes in the last 30 years. There have been significant breakthroughs of controlling stray magnetic and stray voltages. Stray voltage lawsuits have dropped off significantly since updated codes have been put in place.
With that said, we know now how to find stray powers and know how to correct them. In the last 10 to 15 years we have eliminated stray voltage and power issues.
For a solar farm system: They need for their own solar farm electronics systems to be very clean power for their own electronics system. Wires that are direct buried are because of code changes so that there are grounding wires with all power wires. This eliminates with monitoring stray voltages. This also helps to eliminate stray voltages coming in from other grids.
We all work closely for the safety of our people, animals and environment.
