A facility has been developed for the determination of the ratio of pulse high voltage dividers over the range from 10 kV to 300 kV using comparative techniques with Kerr electro-optic voltage measurement systems and reference resistive voltage dividers. Pulse voltage ratios of test dividers can be determined with relative expanded uncertainties of 0.4 % (coverage factor = 2 and thus a two standard deviation estimate) or less using the complementary resistive divider/Kerr cell reference systems. This paper describes the facility and specialized procedures used at NIST for the determination of test voltage divider ratios through comparative techniques. The error sources and special considerations in the construction and use of reference voltage dividers to minimize errors are discussed, and estimates of the measurement uncertainties are presented.
已经开发出一种设备，用于使用克尔电光电压测量系统和参考电阻分压器的比较技术，在10 kV至300 kV范围内测定脉冲高压分压器的比率。使用互补电阻分压器/克尔盒参考系统，可以确定测试分压器的脉冲电压比率，其相对扩展不确定度为0.4%（覆盖因子=2，即双标准偏差估计）或更低。本文描述了美国国家标准与技术研究院（NIST）用于通过比较技术测定测试分压器比率的设备和专门程序。讨论了参考分压器在构建和使用中为最小化误差的误差源和特殊注意事项，并给出了测量不确定度的估计值。
