Correction on the Impulse Scale Factor and Time Parameters of the Reference Divider Based on the Step Response and Convolution

In this paper, a novel method for evaluation impulse scale factor and time parameters of the reference high-voltage divider based on the step response convolution is described. Experiment and simulation results show that the error of the lightning impulse measurement system is approximately equal to the algebraic sum of the differences of the individual cascade components. This conclusion is applicable to the reference system that complies with the IEC 60060-2 specification, and can be used to the impulse scale factor and time parameter corrections of reference divider.
