Abstract：Using cloud-to-ground lightning data obtained from ADTD lightning location system of Zhejiang Province and Ningbo City,detection efficiency of ADTD lightning location system is analyzed. The results show that the number of flashes detected in Ningbo area is far more than the flashes detected in Zhejiang Province. In the reasonable range of detection,the closer the distance between the adjacent detection stations,the higher the detection efficiency,especially the lightning current magnitude from 0 to 30kA. When lightning current magnitude is greater than 50kA,the high proportion of high quality cloud-to-ground lightning data can be detected by the system. Compared with the outside station connection and in the range of station connection,the detection efficiency is high and the proportion of high quality cloud-to-ground lightning data is also relatively high.
