Abstract :
With the large-scale application of 20kV power grid, unified grounding system and transformer vector grouping is critical to the economic and technical performance of the power system. The manufacturing complexity, manufacturing cost and reliability of transformer with different vector group is analyzed in this article, and the applicability of different neutral grounding state in 20kV power system is discussed.
