As the grade of the transmission line voltage increases,the electric magnetic field intensity in the space around the transmission line is getting stronger and stronger.Therefore,the research on electromagnetic field distribution nearby the transmission line is becoming more and more important.Aiming at the difficulty of actually measuring the electric field intensity in the upper space of the transmission line,a new test method is proposed,which adopts unmanned aerial vehicle (UAV) equipped with test equipment to conduct the measurement.Firstly,the real-time data of the electric field intensity and position information are tested,and then the iOSD system is used to compose the tested data in real time.The composed test data are stored and transmitted to the ground control station,then the actual measurement of the electric field intensity in the upper space of the transmission line is achieved.The proposed method was verified through the actual test and analysis of the Zhejiang-Fuzhou 1 000 kV UHV AC transmission line,the test result was compared with the simulation calculation result using Ansoft software.The result shows that the error between the simulated value and measured value is within 7％ when the distance between the test point and the transmission line is within 45 m,which demonstrates the effectiveness of the proposed method.The proposed method has important reference value for the research of spatial electromagnetic environment of transmission lines.
