查询词典 magnetizing method

In the transformer differential protection, it is a congenital and difficult problem that cant be avoided how to distinguish the magnetizing inrush current with the internal fault current. It has become the focus studied for many years. The existing transformer protection principles all have certain defects and the main reason lies in inadequate understand of the transformer fault mechanism.
