- Abstract
- IEC standards do not require to limit the earthing resistance of the concrete-embedded foundation earthing electrode which is installed to a specific value. However, in Korea the value of 5Ω and below applies to the earthing resistance for a domestic customer whose receiving voltage is 22.9kV. This paper calculates the minimum area and volume of the concrete-embedded foundation earthing electrode in order to obtain a specific value of the earthing resistance when the electrode of the building's lightning protection system and that of its power system are interconnected. It also suggested the most appropriate method of installing the foundation earthing electrode, taking the electric characteristics of concrete into account.
