Can anybody point me to a good site that gives an overview of transformers in laymans terms?
I'm building a line conditioner based on a design posted by Jon Risch which is step down tranny caps across the lines and the step up tranny back to 110 V AC. Simple enough, but I want to isolate my flat panel which draws 700 watts.
How do I translate the VA number of the transformer(s) to make sure I have enough tranny to support a 700 watt draw from the flat panel? Is VA equivalent to the wattage already?
Apologies for what is probably a silly question.
thanks

Tpub is an excellent tutorial, IIRC from the US Military.

There's some great information there. Much appreciated!
VA is Watts if your power factor is zero.
The problem with the sort of power level that you are looking at is that the leakage flux and resistive losses will kill you. Way too much current in the secondary.
You really need to look for a 1:1 isolation transformer rated maybe for 1000W.
Don't fry yourself...

Actually, VA is Watts if your power factor is unity (one).
For a given wattage, VA increases as power factor falls below one.
"For a given wattage, VA increases as power factor falls below one."
Yup.
