MAGNETIZING INRUSH CURRENT SUPPRESSION DEVICE |
摘要 |
There is provided with a transformer inrush current restraining control equipment that provide useful practice to effectively restrain transformer inrush current which would be inevitably caused whenever a transformer under out of service is going to be put into operation by the related breaker closing operation. The transformer inrush current restraining control equipment 10 includes a voltage measuring unit 1; a true residual fluxes timing calculating unit 2; a core-flux calculating unit 3; a true residual flux calculating unit 4; a breaker closing phase angular timing calculating unit 5; a breaker closing phase angular timing controlling unit 6. |
