Investigations of earthing components corrosion in different climatic conditions

The paper is addressed to studies of earthing system components corrosion in different climatic conditions based on comparative field tests results from Poland, North Africa and China. The paper is continuation of the paper presented at ICLP 2010 in Cagliari, and contains discussion and analyses of new field corrosion tests and observations performed in Sudan, which is located in warm, dry (arid), desert climate.
