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. Ver mais Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Alternating-current electric motors and transformers may … Ver mais When a transformer is first energized, a transient current up to 10 to 15 times larger than the rated transformer current can flow for several … Ver mais Metals have a positive temperature coefficient of resistance; they have lower resistance when cold.
