摘要：
Based on the safety evaluation, the multi-aspect assessment concept of large grounding grid was presented, which covered ground potential time-space distribution characteristics, current disperse characteristics, potential equalizing performance and health condition. The checking principles and methods of ground potential rise based on the energy absorb of 10kV arrester and cable sheath protector during fault, ground potential difference (1000V), ground impedance and corrosion diagnosis based on both electrical and soil physicochemical properties were recommended, together with the corresponding solution, which were of great reference value for both design and safety evaluation of large grounding grid. © 2018 Chin.
