This research aimed at the improvements of the measuring techniques ofr high voltage and high current impulses and the following results have been obtained.1. A high accuracy reference impulse generator has been developed for the calibration of impulse measuring systems. The accuracy is within <plus-minus>0.3% for the generated impulse crest valuテ2. In order to measure the standard impulse (1.2/50 <micrn>s) within the errors specified in the IEC publicaton 60, it is necessary to use a digital recorder with sampling rate above 40/<micrn>s and resolution above 8 bit.3. The Numerical Laplace Transform is one of the effective methods for reconstructing the input impulse wave using the measured impulse wave and step response wave of the measuring system. However, in this case, the reading errors of these measured wave form should be as low as possibel.4. By using a by-pass capacitance on a part of the high voltage arm of a resistance divider or an inductive resistor as the low voltage arm, the response of the impulse measuring system could be improved considerably. Especially, the combination of these methods improves the response remarkably.5. An electrolyte resistance-capacitance divider with high quality for impulse measurments has been developed by utilizing the large dielectric constant of the electrolyte.

这项研究旨在改善高压和高电流冲动的测量技术，并获得以下结果。1。已经开发了高精度参考脉冲发生器，用于校准脉冲测量系统。对于生成的Impulse Crest valute2，精度在<Plus-Minus> 0.3％之内。为了在IEC Pubulaton 60中指定的错误中测量标准脉冲（1.2/50 <mincn> s），有必要使用以高于40/<micrn> s的采样速率的数字记录器，并且分辨率高于8位。3。数值拉普拉斯变换是使用测量系统的测量脉冲波和步进响应波重建输入脉冲波的有效方法之一。但是，在这种情况下，这些测得的波形形式的读数误差应尽可能低。4。通过在电阻分隔器或电感电阻器的高压臂的一部分上使用旁路电容，作为低压臂，可以保守地改善脉冲测量系统的响应。特别是，这些方法的组合可以显着改善响应5。通过使用电解质的大介电常数，已经开发出具有高质量脉冲测量的电解质电容性分隔器。
