    Abstract: Introduction was made to the types of sway electric produced by the power supply system of refinery. Analysis was made to the impacts of sway electric on the normal running of motors, low-voltage switchgear, process control system and instrument power supply.Combined with anti sway electric rebuild example of certain refinery power supply system, this paper sums up three measures of anti sway electric rebuilding of the refinery power supply system, demonstrating the validity of these anti sway electric measures and giving some suggestions of anti sway electric.
    Key words: refining enterprises; anti-sway electric; power supply system
