Feasibility Study on Voltage Sensors for Measuring Power Factor Mounted on Transmission Lines.

概要

In general, since voltage in transmission lines is so high that the wave form need to be measured with static induction type of voltage sensor, which comprises a pair of electrodes, there should exist a problem on the discrepancy between the actual voltage wave form and the measured one in three phase power distribution systems owing to the mutual electric induction between each other phase.We shall present the numerical electric field analysis of the sensors in such a power distribution system using two dimension finite element method taking account of the unknown equi-potentials and the complex permittivity to clarify the difference between the impressed voltage wave form across the electrodes of such a sensor and the actual voltage wave form.
