摘　　要：电磁式电压互感器通常在现场利用测差法进行测试,对于35 kV及以上的电压互感器检定,在现场条件下就显得不便。为此近年来国内外开展了采用低的工作电压测算高压互感器误差的技术研究,通常称为低校高法的现场电压互感器误差测量方法,文中描述的是该方法的一种数学建模研究,通过研究数学模型,更好地学习理解该方法与测差法的差异,提高低校高法的测量准确度水平。Electromagnetic voltage transformer is usually using the differential method to test at the scene,for the 35 kV and above voltage transformer calibration,at the scene under the condition of it is inconvenient,so in recent years at home and abroad to carry out the research by low voltage measurement of high voltage transformer error,usually referred to as the scene of voltage transformer error measurement method of low high school law,this paper describes a mathematical model of this research method,through the research on the mathematical model,the difference is better learn to understand the method and differential method,improve the low accuracy of measurement of high school level.
