摘要:
小电流间接法检定电流互感器是在小电流状态下测被检互感器的误差和相关参数，并在此基础上外推至额定电流及额定负荷和下限负荷下的误差，无需大电流电源。采用小电流间接法检定现场电流互感器时可能会受到外界干扰，影响测试准确度。改进后的小电流间接法，采用传统比较测差法在小电流下测试并推导误差函数，准确测定被检互感器的励磁导纳和比值差补偿值，有效消除外界干扰的影响，保证了测试准确度，适用于检定现场电流互感器。
Abstract:
Under the indirect method of testing a small current of current transformer is measured the tested transformer error and associated parameters in small current condition, and on this basis , extrapolation to the rated current and the rated load and lower load of errors, without the need for high current power supply.. May be subject to external interference by small current indirect verification of current transformer on site, affect test accuracy, small current indirect method improved, using the traditional method of comparing the measured differential in small current test and derivation function, accurate determination of the tested transformer excitation admittance and the ratio difference compensation value, effectively eliminate the impact of external interference, to ensure the testing accuracy, suitable for verification of current transformer on site.
