南京地震台地电阻率观测因南京地铁的建设和运行受到干扰，故在距南京100KM左右的高淳重新选址建设，现已投入正式观测，运行模式为无人值守有人看护。地电观测系统自建成以来，每年雷雨季节观测系统遭受雷击多次，最为严重的是2010年9月10日的雷电，此次雷电造成在用仪器损毁严重，不得不中断观测，把仪器发往厂家维修。本文研究雷电对地电观测项目造成雷击灾害的成因，从而采取有效的应对措施，最大程度的提高数据的连续率。

Nanjing Seismological Observatory resistivity observed of interference due to Nanjing subway construction and operation, it is about 100Km away from Nanjing Gaochun to rebuild and in a formal observation now. Unattended operation mode for the care of someone。After the formal observation，observation system was struck by lightning several times in thunderstorm season each year, the most serious is September 10, 2010, the lightning caused serious damage to the instruments and had to interrupt observations, the maintenance of equipment sent to the manufacturers. In this paper, observations of lightning on the ground caused by lightning disaster in the project to take effective measures to deal with the maximum continuous data rate of increase.
