Publication of IEC 60060-2 concerning for High Voltage Measurements and Test Techniques was revised in 1994 and requires each member country to have high voltage measuring system traceable to national reference. Japan, according to the requirements, has been mandated to install national reference system and reference system. Needless to mention, these measuring systems must have excellent response enough to calibrate commercial measuring systems. Candidates for the requirements targeting 500〜700kV class system are 1)oil-insulated resistive divider, 2)multi-shield type compensated capacitive divider, 3)resistive divider with high voltage ring shield, 4)damped capacitive divider and 5)filed probe. Authors investigated the possibility to use field probe in lightning impulse voltage measuring as the probe system has superior performance to the others in linearity, temperature dependency, long-and short-term stabilities as well as polarity effect. A conventional field probe used in measuring commercial frequency AC voltage has been pointed to have fatal characteristics : 1)small gain and 2)wave distortion due to impedance matching when used in measuring fast phenomenon like lightning impulse voltage measurement. Researchers involved in this project have completely overcome these difficulties by introducing a resistive cable and developed a system adequate to be a reference measuring system fulfilling requirements defined in IEC 60060-2.

IEC 60060-2关于高压测量和测试技术的出版物于1994年修订，要求每个成员国都有可追溯到国家参考的高压测量系统。日本根据要求，已被授权安装国家参考系统和参考系统。不用说，这些测量系统必须有足够好的响应来校准商业测量系统。针对500 ~ 700kV级系统的候选要求有：1)油绝缘电阻分压器，2)多屏蔽型补偿电容分压器，3)高压环形屏蔽电阻分压器，4)阻尼电容分压器和5)场致探头。由于现场探头系统在线性度、温度依赖性、长短期稳定性和极性效应等方面都优于其他探头系统，探讨了将其应用于雷击电压测量的可能性。传统的用于测量商用频率交流电压的现场探头具有致命的特点：1)增益小；2)在测量雷击电压等快速现象时，由于阻抗匹配导致波形失真。参与该项目的研究人员通过引入电阻电缆完全克服了这些困难，并开发了一个足以作为参考测量系统的系统，满足IEC 60060-2中定义的要求。
