@@@@The 500 kV power grid is developed rapidly to be the main framework terminal network at the present stage , and is related to the safe and stable operation of the whole grid .So the relevant commissioning acceptances of protection and control circuits etc.are particularly important during the construction preparation .Taking the existing typical defects finding in the tripping loop of low side switch in main transformer in a newly -operated 500 kV substation for example, the troubleshooting and discrimination ideas and methods are described in detail , and some effective precautionary measures are put forward to control and solve the similar defects, which provides the favorable references for the similar construction acceptance and com -missioning work.
