摘要： A closing phase that produces the smallest energization flux error at a connection input point is calculated based upon a residual flux of the first closing phase and the preliminarily given pre-arc characteristic and closing time deviation characteristic of a three-phase circuit breaker, so that the calculated phase value is set as a target closing phase of the first closing phase. A closing phase that produces the smallest energization flux error when a residual flux of zero is calculated, so that the calculated phase value is set as a target closing phase of the remaining two phases. The total time required from the reference point to the target closing phases of the remaining two phases and a delay time corresponding to an integer multiple of a given cycle of the three-phase power supply is set as a target closing time of the remaining two phases.

摘要： A target closing phase determining circuit determines energization flux errors in respective phases and respective closing phases of a first phase, and determines a target closing phase of the first phase so as to minimize an evaluated value related to determined energization flux errors in the respective phases. Each of the energization flux errors is the maximum value of absolute values of center values of transformer fluxes generated in a static state after energization. The target closing phase determining circuit determines the energization flux errors based on residual flux values for the first to third phases of a three-phase power supply, respectively, a pre-arc characteristic and a closing time variation characteristic of a three-phase circuit breaker, a connection condition of windings of a three-phase transformer, to which the three-phase circuit breaker is connected, and voltage phase differences among the phases of the three-phase power supply.
