Abstract
This paper analyzes Henan power circuit breakers with closing resistors operation. Selecting a typical substation as the research object, switching overvoltage and surge arrester energy absorption were simulated without the closing resistor. Measured through the field test verified the accuracy of the simulation. The relations between line length and over-voltage level was also analyzed. The result provides the foundation for selection of new construction and breaker transformation.
