Description

Technical field [0001] The invention is a device that can effectively reduce the response time of the step response of the resistance voltage divider and improve the performance of the voltage divider, is suitable for the measurement of high voltage pulses, and belongs to the technical field of high voltage measurement. Background technique [0002] The error generated by the resistance voltage divider when measuring the impulse voltage is related to the product of the resistance value and the stray capacitance to ground. Therefore, the error can be reduced by reducing the resistance and reducing the stray capacitance to the ground. However, if the resistance is too small, on the one hand, it will have an impact on the generator's shock wave. On the other hand, it is difficult to dampen the oscillation between the residual inductance and the stray capacitance, and the resulting step response will produce a higher overshoot. Therefore, reducing the measurement error is mainly focu...
