In this paper, a high-speed, high-voltage capacitive voltage divider (CVD) for impulse measurement was designed and fabricated. The impulses generated during accidents such as railway applications are generated by wave-forms with high rise time and high peak value. The voltage dividre has been improved on the basis of a CVD. A CVD has a large partial voltage ratio and is suitable for high voltage applications; it has a simple structure. Designed to meet the target voltage, the circuit is designed for fast rise time by reducing the stray inductance. The fabricate CVD was verified under various conditions in comparison with a commercial probe. Experimental results show good results in the form of high measured voltage and rising waveform. Device can be applied to research into high voltage impulse applications that have rapid rise time, such as lightning, accident current, etc.
