| Abstract: | The reasons, in the protection mode with positive pole of voltage component set earthed, why the mode without frame protection is not suitable to use, while the mode with frame protection is selected, are explained. In addition, how to cooperate the protection with positive pole set earthed and the voltage monitoring setting value of track short circuiting device is also introduced. |
