A New Consideration on a Resistor Divider for Impulse Voltage Measurements

Response characteristics of a resistor divider whose high-and low-voltage arms consists of different characteristic elements are investigated and theoretical response equations to the unit step, triangular wave, and exponential front wave are derived. Detailed numerical calculations are carried out on the response of such a resistor divider and error for measuring the impulse chopped on the front and the optimum shunt capacitance value to minimize it are clarified.
