摘要
讨论和分析了山西省省对地关口计量装置存在的互感器准确度等级达不到要求、互感器配置不合理、电压互感器二次回路压降超差等问题，提出了为提高计量装置的准确度应采取互感器合理配置和减小电压互感器二次压降的方法。
The problems of the transformer precision,transformer arrangement and PT second circuit voltage difference measuring equipment in Shanxi province are discussed and analyzed in detail.It proposes that it should take measures to optimize transformer allocation and low down the voltage difference of PT second circuit in order to imcrease the precision level of the present equipment.
