N2 - In this paper, a new technique for high voltage measurement for DC and AC systems using High Voltage Electric Field Motor (HVEFM) is proposed. The rotor speed of HVEFM is linearly proportional to the applied voltage. Therefore, the input voltage can be measured by detecting the rotor speed. The range of the measured voltage level is dependent of the pressure and types of gases in HVEFM. The structure is a significant factor affecting the accuracy of measurement, and a range of measured voltage level. The Finite element (FEM) program is used for computing the voltage level and electric field distribution at any points of HVEFM. The calculated results offer a design of the appropriate structure, so that the relationship between the motor speed and measured voltage level is linear and measurement can be applicable to higher voltage level. The advantages of this technique are light, compact, easy to install, and low cost when comparing to a conventional divider technique.
