Grounding Reference
1.2 The ‘Frame Ground’ and ‘Grounding Bar’
Figure G-2: Grounding Bar.
According to previous description, the grounding is the most impor-
tant issue for our system. Just like ‘Frame Ground’ of the computer,
this signal offers a reference point of the electronic circuit inside the
computer. When we want to communicate with this computer, not only
‘signal ground’, but also ‘frame ground’ should be connected to make
a reference point of each other’s electronic circuit. Generally speaking,
it’s necessary to build a individual grounding bar for each system,
such as computer networks, telecommunication networks, power
system, . . . , etc. Those individual grounding bars not only provide the
individual reference point, but also make the earth as a real ground!
Neutral is the physical cable from Generator.
Ground is the local physical cable that connected to
