Simulation of the relationship between sensor size and minimum space of applicable electric field based on ANSYS
The electric field distortion caused by the power frequency electric field measurement sensor in a narrow space can change the original electric field distribution,leading to a large measurement error.A simu-lation model for the relationship between sensor size and the size of the measured space is established,and the distortion impact assessment indicators is defined.ANSYS software is used to simulate the relationship between the sensor size and the minimum spatial size suitable for measurement,and the influence of the sensor size on the electric field distortion is analyzed.The spatial scale of the measured electric field under different sensor sizes is simulated and analyzed.Through the trend fitting of the simulation results,the quantitative relationship expression between the sensor size and the minimum spatial size applicable to measurement is finally obtained.
