How to calculate split factor grounding
WebIn this paper, a novel, simple and accurate method is developed for the determination of split factor. In the proposed algorithm grounding grid impedance of adjacent … Web1) We calculate the resistance to heat transfer of the wall, dividing the thickness of the material by its coefficient of thermal conductivity. For example, if the wall is built of warm ceramic 0.5 m thick with a thermal conductivity coefficient of 0.16 W / (m × ° C), then we divide 0.5 by 0.16:
