Modelling of Building Lightning Protection Parameters

A lot of research is being performed in the field of lightning protection, beginning with lightning parameters and object reactions to these parameters, ending with electromagnetic wave propagation inside the object. All this is becoming very important with increased usage of microprocessor equipment. Several methodologies and various computer modeling programs are created which allow to determine the electric potential distribution during the lightning strike in 3D (precision of resistance calculation are parts of ohm and in case of electric potential - parts of volt). However there is still a problem pending - how to select the lightning protection equipment correctly? In this work the simplified method of calculation of lightning protection devices is presented which is based on the acquired experience and research of other scientists in this field. This method allows to determine the grounding resistance and electric potential distribution in the elements of lightning protection. Data obtained by applying this method will allow more precise selection of lightning protection devices.
