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
