摘要
作为电网系统的重要单元,电流互感器对电能计量具有十分重要的作用,其误差试验的正确性和准确性关系发、供、用三方的切身利益。随着电压等级的不断提高,电流互感器检定试验对试验电源容量的要求越来越高,为提高试验电源使用效率,采用可调式电流互感器补偿装置,通过线性可调无功补偿,提高功率因数,使用有限容量的试验电源,完成高电压等级的电流互感器误差试验检定工作。
As an important unit of the power grid system, the current transformer plays a very important role in the measurement of electric energy, the correctness and accuracy of the error test are related to the personal interests of the three sides about power generation, power supply and customers. With the constant improvement of the voltage class, the demands of the current transformer verification test for the test power capacity are higher and higher, in order to improve the efficiency of test power use,the compensation device of adjustable current transformer is adopted, the power factor is improved through the linear adjustable reactive power compensation, and the verification tasks of HV class CT error test are implemented by the use of experimental power supply with limited capacity.
