Measurement and calculation method of substation grounding system parameters based on CDEGS

open access: yesJournal of Physics: Conference Series, 2022
Abstract Indoor substations are often located in areas with intensive power consumption, and its grounding design has become a very important task. In this paper, the whole process of grounding design is studied from the grounding resistance measurement obtained in the early geological exploration to the final grounding resistance, touch
