Through the investigation of the root cause tor each lightning strike, the main reason and problem on site are identified, and the complete lightning surge protection measures are drawn. Internal and external lightening surge protection modification are conducted continuously in pipeline offtake station and valve station, including direct lightning strike protection, inductive lightning strike protection, power supply and signal surge arrester modification, and modification of unreasonable original electrical and instrument design etc. Good lightening surge protection effects have been achieved. It can be used as reference for lightening surge protection to other natural gas pipeline projects.
