A 12 hour day at work and you figure during that time I would have an opportunity to look up the information on our fencer indicator design. But it was a busy day and I couldn't. I wanted to get some details but I will just briefly mention it now. We needed to add an indicator to show the fence condition. I don't really want to call it a voltage indicator as the range might not have been linear. But it did show different loading so it did what it needed to.
We added a wire through one of the output transformer's lamination holes. Not in with the high voltage wire's window area, but through the holes in the E portion.
It was away from any high voltage. We used one turn through that hole and got enough signal that we could send through a diode and into a capacitor. The voltage on the capacitor was measured by a bar graph display chip. It was quite effective.
I'l try and get more details but it would be on Tuesday if I can remember. (Long Weekend here
