Earthing - Industrial building

Setting a safe basis

Whether existing or new buildings, a functioning earth-termination system is the prerequisite for the safe operation of electric systems in buildings and for protecting people from dangerous high voltages.

The design and implementation of the earth-termination system are of central importance. After the concrete has set, it is no longer possible to change the earthing concept based on e.g. a foundation earth electrode. Omissions or errors during the construction phase cannot be corrected later or, at least, not without a great deal of effort and expense.
