Who owned Toroidal Isolation Transformers like this:
Do you have a gaussmeter (or any magnetic field meter like the following)?
How low did you measure the magnetic field of it compared to a normal transformer? Is it one half or 1/3 or even lower?
I need very low magnetic field for some applications. In my testing. When I put the above EM meter 16 inches away from a normal transformer. I was getting 100 milligauss. I need it to be 20 milligauss or lower.
This is for one without Mu-Metal shielding.. and what did you measure when you add Mu-metal shielding?
