The Influence of ±800 KV Cirque Grounding Electrode Circuit Commissioning on Soil Temperature and Physicochemical Properties
During the commissioning (alternate unipolar and bipolar operation) of ±800KV DC transmission grounding electrode, the average grounding current is much greater than that of the steady bipolar operation, which might cause undesirable impacts on the edatope. In this study, the soil physicochemical property variations of the plant root zone (depth 0.5 m) and the soil temperature during the commissioning of the grounding electrode were monitored and analyzed. And the influence of the commissioning on plant growth was evaluated.
