Post Subject: bad electricity or bad wiring?Posted by buzz on: 7/2/2007
Hi Romy,
I just wanted to mention that 'ground' in home ac is not 'ground' at all. It is actually 'neutral', a theoretical '0 volts'. In reality the resistance of the wire itself guarantees that there WILL BE voltage on that wire. Remember, voltage will always follow the path of least resistance. If you tie a seperate copper grounding rod to your system, any other component (refridge or your neighbors air conditioning) using the same line voltage may chose to use that path instead of the city power grid. In the very least, a giant ground loop has been created, with your system right in the middle. The end result is an INCREASE in noise. The mention of "wetting" a grounding rod shows how severely flawed a system can become.
I have had great success using derived 'ground' and isolation transformers. While not a total solution, they have proven highly stabile.Rerurn to Romy the Cat's Site
