The area with insufficient bedrock thickness faces a high risk of water-sand inrush, and a poor mine design can lead to serious water–sand inrush incidents. Inrush current can be divided in three categories: Energization inrush current result of re-energization of transformer. The residual flux in this case can be zero or depending on energization timing. Recovery inrush current flow when transformer voltage is restored after having been reduced by system disturbance.
