Research on the Configuration of Zero Sequence Current Transformers Under 10?kV Low Resistance Grounding Mode in Substations
In order to achieve precise configuration of zero sequence current transformers under 10 kV low resistance grounding mode,the article takes A substation as an example to comprehensively analyze the 10 kV low resistance grounding system and zero sequence current situation of the substation.Based on actual data,the article proposes the configuration strategy and method of zero sequence current transformers under 10 kV low resistance grounding mode.Finally,through experimental verification,it was found that the efficiency of the zero sequence current transformer configuration strategy is much better than traditional configuration strategies,and has high practical promotion value.
