The magnetic field of dry-typeaircorereactor with spatial closed loop is calculated with analytic method. And the effect of closed loop on parameters of a reactor is explored.
With the parameters of a real dry-typeair-corereactor, the emulation analysis verifies that the impulse-voltage method is suitable to test its turn-to-turn insulation.
