摘　　要：随着大量1000kV、765kV电容式电压互感器(CVT)在特高压电网中的使用,为了保证现场CVT误差校验数据质量,使其单次测量可直接溯源到国家基标准,在1000kV串联式标准TV误差原理及结构特点的基础上,采用实验室计量保证方案(Map)的闭环量传控制思想,针对现场CVT误差校准试验特点,设计了适合于现场校准特点的误差计量保证方案。该方案已用于青海750kV西宁变电站CVT现场误差校准试验,并成功地分析判定了对试验中遇到的典型事例。Based on the error principle and structural characteristics of 1000 kV series standard TV, this paper proposes a design of error measurement assurance program which is suitable for field calibration, with the large number of 1000 kV, 765 kV capacitor voltage transformers （CVT） in the use of ultra high-voltage {UHV） power grid. In order to ensure the quality of field CVT error calibration data and then a single measurement can be directly traceable to national standards, the design follows the thought of closed-loop transmission control in laboratory measurement assurance program [MAP）, according to the characteristics of on-site CVT error calibration experiments. The program is carried out in Xining{ Qinghai province} 750 kV substation in CVT field error calibration tests and typical cases are successfully analyzed and determined accordingly.
