Abstract: Taking 500kV Wuyi substation as an example, this paper analyzed application functions and cautions for operation of the device from the configuration of capacitive DC blocking device, basic principle and control mode etc aspects. The actual application indicates that the method that the neutral point circuit of main transformer No.2 was connected in series to the capacitive DC blocking device eliminates the impact of DC current component in earth system on the main transformer, which reduces losses, assuring operation of the main transformer.
Key words: transformer; neutral point; DC current; capacitive DC blocking device
