【Abstract】 Based on the basic principle of electromagnetic field, a formula to calculate the phase-to-phase electromagnetic force in non-coaxially assembled three-phase air-core power reactors is presented. The electromagnetic force can be easily calculated by a numerical integration. This provided the foundation and facility for the checkout of dynamical stability of three-phase air-core power reactors at design stage. The formula can also be used for the calculation of the phase-to-phase electromagnetic force in a system failure condition.更多还原
