PROBLEM TO BE SOLVED: To obtain a set value for correcting the time taken to switch a circuit breaker from the state quantity of the circuit breaker in operation. SOLUTION: A system includes a control section 100 for controlling switching of the circuit breaker and a setting control section 700 connected with the control section via a network 500. The control section 100 for controlling the switching of the breaker sends the state quantity of the circuit breaker to a set value calculating-and-processing section 740 of the setting control section 700 via the communication network, the state quantity being obtained by a signal input section 120. The set value calculating-and-processing section 740 of the setting control section calculates a set value to which the control section 100 for the circuit breaker is set, using the state quantity of the circuit breaker sent. The setting control section 700 sends the set value calculated by the set value calculating-and-processing section 730 to the control section for switching the circuit breaker, via the communication network. An arithmetic processing section 140 mounted in the control section for switching the circuit breaker and used for control of the switching corrects the circuit breaker switching actuation time based on the set value, and calculates a delay time relative to a zero-cross point based on this corrected switching actuation time and on a power system period.
