Installing foundation earth electrode
2." Also:
• "Conductive element, embedded the earth in
another specific conductive medium electrical
contact with the earth.4 Earthing systems
The standards specify that each system must include
an earthing system."
The tasks earthing system are:
• Arresting the lightning current into the earth
• Equipotential bonding between the down-conduct-
ors
• Equipotential bonding near conductive walls the
building structure
Consequences improperly created earthing
system:
• Dangerous surge voltages the equipotential
bonding
• even potential course the earthing system
• Destruction the foundation through insufficient ar-
resting area the energy-rich lightning current
• Destruction the foundation through improperly
made connections (no terminal connection)
• Electrical decoupling high amounts lightning
energy
