一、检定设备感应分压器相对检定时,应有一台标准的多盘感应分压器,作为比对的标准,同时要求指零系统有屏蔽保护措施,消除泄漏影响。此外,还要求有电势可调的微差补偿器,能够同时调节同相分量和正交分量,以便测得两台感应分压器之间的差值。设标准分压器的比率误差为δ_s,被检分压器的比率误差为δ_x,其差值(δ_x-δ_s)采用微差补偿器进行补偿,其补偿值为△_i,以此使 First, the test equipment relative voltage divider detection, there should be a standard multi-plate sensing voltage divider, as the standard comparison, also called zero system shielding protection measures to eliminate the impact of leakage. In addition, there is also a potential-compensated micro-compensator that can adjust both the in-phase and quadrature components simultaneously to measure the difference between the two sense dividers. Let the standard voltage divider ratio error δ_s, was seized voltage divider ratio error δ_x, the difference (δ_x-δ_s) by using the differential compensation, the compensation value △ _i, in order to make
