The functional earth equipotential bonding mechanism
that used discharge shield-coupled transient currents. It
can also have earth function prevent sensitive devices
from damage. Even the symbols used here have been
extended order clarify the functional earth. This creates so-called “clean“ earth because
compensation currents are not possible when this type of
wiring used.
