Having trouble finding good resource material on these three. Any help would be appreciated!
What are the main differences and their main uses?
Also- on a grounding transformer(the ones we are testing), the Impedance is measured in ohms and not as a percentage. Could someone explain a little more about that?
Ty all again!!!
