Three grounding methods of optical ground wire ( OPGW) are adopted in ultra -high voltage transmission network , that is, grounded at every tower , grounded at one single point in one line section and grounded at one single point insulated entirely in whole line .Various aspects of OPGW projects such as the implementation of grounding equipment and installation , the normal operation condition , the fault state , lightning protection performance , operational maintenance and reliability etc . will be affected by different grounding methods .The comprehensive analysis and comparison among three grounding methods of OPGW are carried out and the suggestions are provided to the engineering design and operation for reference .
