The current corona measurement method cannot conduct direct measurement for the corona of operating transmis -sion line,the corona loss can be calculated by film sensor's measurement of the current running outside the wire and between the double membranes.The system consists of acquisition front-end based on FPGA,the transmission system based on 3G network and the computer.The measurement device has conducted experiment on 150 kV analog line set up in the laboratory,and the corona loss of transmission line under different voltage grade has been successfully measured.The research shows that the disturbance of using film sensor to measure the corona loss is negligible and the measurement of it is convenient,which is appropriate for the co-rona loss research and transmission line's technical line loss monitoring.%现有的电晕测量方法无法对运行中的输电线路电晕进行直接测量,通过薄膜传感器测量运行导线外双层膜间电流,可计算出电晕损耗量,系统由基于FPGA的采集前端、基于3G网络的传输系统和计算机组成,制作的测量装置在实验室搭建的150 kV模拟线路进行了实验,成功测得不同电压等级下输电线路的电晕损耗.研究表明,利用薄膜传感器测量电晕损耗干扰小、测量方便,适用于电晕损耗研究和输电线路技术线损监测.
