Transformer demagnetizer

STDE Power transformer demagnetizer

This option allows neutralizing the residual magnetization of the power transformer core after the winding resistance test. The principle of the option is to apply a constant current of alternate polarities to the transformer winding, as per the IEEE 0062 1995 standard.
