3.3 Connecting a Ground Cable
Grounding involves not only stabilizing the complicated electrical and electronic systems,
such as power, transmission and control systems by protecting them from lightning,
excessive electricity or voltage inflow, and electric noise, but also protecting from
accidental electric shocks.
The grounding system prevents an electrical charge between the ground and the installation
unit by connecting all equipment to the ground in order to keep the electric potential close
to 0, which is the grounded electrical level.
When connecting the system, connecting the cable, or maintaining the system
without the ground cable connected, the system can be damaged due to static
electricity and short circuit, which may result in an electric shock to the operator.
The purpose of grounding is as follows:
To protect human lives and electrical systems from lightning, excessive electricity
surges, or high voltage.
To provide a discharge path for a surge caused by lightning or electricity.
To protect the system from static electricity.
To remove or reduce the potential for a high-frequency electrical overload inside the
system or the unit.
To provide a conductor for the high-frequency electrical output to be equilibrated and
stabilized.
To stabilize the electric current from the grounding circuit.
