Design of an Accurate Contactless Voltage Probe Including a Signal Processing Circuit

This paper demonstrates a design technique of an accurate contactless voltage probe. The basic theory of electrostatic field for this design is mentioned firstly. Then, for accurate measurement and EMI consideration, a dedicate electrode, a filtering and amplifying circuit, and a shielding chamber are designed. Measured signal by this device is also presented as a method confirmation.
