Seasonal Influences on the Impulse Characteristics of Grounding Systems for Tropical Countries
One of the most important parameters of the performance of grounding systems is the soil resistivity. As generally known, the soil resistivity changes seasonally, hence the performance of grounding systems, at DC and under high impulse conditions.
