What is happening is called "induction" This is the same thing that your transformer does. Volts per turn is the formula for changing from a high voltage to a low voltage. 138000 volts on the primary side, 8000 volts on the secondary side, you need a conversion of 17.25. So your 138 KV primary needs 17.25 times as many turns as your 8 KV secondary. Many people have died from induction. I have worked on a 138 KV line that was dead and grounded 10 feet either side of me. But it was within 20 feet of a live line. Without the grounds I would have been killed or at a minimum very badly burnt. It was so "hot" in my bucket that sparks were going between my tools. So if you want to power your big amps, just take a large number of grader blades (this will be your core) wind common bi-plex around them until you have 120 volts across each winding. Connect the windings so they are additive and there you go. Voltage regulation will be poor depending on how much power is flowing in the HV over head line and how many amps you are pulling from your home brew transformer. (I didn't tell you to do this, and I will disavow any knowledge of your actions ;-) Peter VE6YC 25 years as a lineman _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more.
