DC method: according to the electrical theory XHXC105 demagnetizer is a direct current through the reverse direction, and gradually reduce, decrease the hysteresis loop of the core, to eliminate the purpose of residual magnetism. Direct current is passed into the high-voltage winding of the tested transformer (the three-phase transformer is only sufficient for B-0 or A-C degaussing), for example, 5A, its demagnetization current is not less than the test current of the high-voltage winding. The DC demagnetization ends when the current is 0.5 Ma.
