VOLTAGE MEASUREMENT DEVICE

摘要

In order to provide a voltage measurement device that can measure the DC voltage of a measurement target without making contact with same, this voltage measurement device is provided with the following: a dielectric provided so as to be able to face a conductor being measured; an electrode provided on said dielectric; a capacitor that, when connected to said electrode, holds an electric potential that exhibits a one-to-one correlation with the electric potential of the electrode; and a switch provided so as to be able to connect the electrode and the capacitor to each other and also provided so as to be able to output the voltage across the terminals of the capacitor when the electrode and the capacitor are disconnected from each other.
