My question is how to build a artificial ground? Asume you have a house with no ground wire running to each outlet. When you plug in a component, its operation is based on an internal ground to the chassis. Some wire manufactures use a artificial grounding box for their sheilds on the cable.
What is the most effective and space limited form of material/configuration for a artifical ground?That "ground" wire running to each outlet isn't really there to serve as a ground reference. It's there for safety purposes. The chassis of most high-end gear aren't double insulated and in the event that the AC line's "hot" wire contacts a metal chassis, it would present a shock hazard to the user. With the chassis connected to the safety ground, the safety ground becomes the low-impedance return path for the "hot" lead instead of the user.
Some older homes that don't use three-prong outlets still use three-wire AC wiring with the wire attached to the metal outlet box. If that's the case in your house, you can use three-prong outlets and wire the safety ground to the outlet box. But that's only for safety purposes. I don't understand why you want to create an "artificial" ground.
