Electric field measurement under high voltage overhead transmission using a high-performance MEMS electric field sensor is presented. To study the distribution of electric field under high voltage overhead transmission lines

based on the charge simulation method

a generic model for two-dimensional electric field calculation is established. To measure the electric field distribution

a novel measurement system of wireless transmission based on high-performance MEMS electric field sensing chips is introduced. Tested in ambient air conditions

the minimum detectable field of the system is approximately 20 V/m

with an uncertainty of 1. 53 % in working frequency electric field range 0

1 000 kV/m. The simulation

and test results show that the deviation between the calculation results and the test results of the system for electric field under 35 kV and 10 kV transmission lines is 6 % and 10 %

respectively

and the plotted curves of the system are consistent with traditional Narda EFA—300 electromagnetic field analyzer.
