Existing approach to the implementation of the
grounding of technical systems
Key words:
Grounding system, touch voltage, step voltage, computer modeling,
grounding resistance.
As technological and process requirements change, the demands for the quality of
grounding change, too.
Using the FOP test, the
grounding system being tested must I be disconnected from the equipment being I grounded, de-energized, and isolated--but this can be impossible to do in an operating industrial facility where output and processes must be maintained.
Experience that you too, can send your roots deeply into the earth for nourishment and
grounding. You too, with steady, deep breath, can draw earth nutrients up through your roots, feeding your trunk, branches, and every part of you.
Companies can choose to protect their facilities with a variety of systems, including ungrounded, solidly grounded, low-resistance
grounding and high-resistance
grounding.
If you have a car frame, you can eliminate the wire returning to the low voltage terminal by
grounding the return wire to the frame, and allowing the current to flow through the steel metal of the frame.
Due to the distances between the system grounds, there can be significant differences of potential between the local
grounding points.
Here's the rub: You won't notice that the
grounding circuit isn't working in normal day-to-day living.
These
grounding connections that bridge the wiring and pipes (which constitute an additional pathway by which a current may travel) force both systems to carry precisely the same voltage -- something they might not have done otherwise.
Grounding one of them was easy: it's at the bottom of the mountain, where soil conditions are standard (3000 to 4000 psi) in bearing-surface measurements.
Grounding is accomplished by connecting the device, through a conductor that carries no current under normal conditions, to the earth.
