| Abstract: | Though the repeated operations and tests of the electrical blocking circuit for 220 kV disconnector, it is found that the capacitance to earth of ground bus forms a AC on - circuit in the electrical blocking circuit which leads to the failure of electrical blocking, And the specific preventive measures are put forward. |
