Precision Capacitive Voltage Divider for Impulse Voltagge Measurements

Abstract

This paper describes a precision capacitive voltage divider for impulse voltage measurements. The main feature of the new divider is a compressed-gas capacitor in the high-voltage arm. The divider is insensitive to environmental influences, possesses outstanding high-frequency properties, and causes little loading of the high-voltage circuit. Its excellent linearity and stable ratio permit meaningful high-voltage pulse measurements in the megavolt range.
