Dirty Earth is a connection between all the AC elctrical
Earth and Clean Earth is an earth which is used for DC
power. Both of this two earth will eventually conect
together at the service point where it is going to go to
the earth Net or wells. The difference is that they do not
want to mix this two earth together till the end point and
the reason is to avoid any earth loop between diferent
devices or earth at the plant.
