System and method of over-voltage protection |
| 摘要 |
In one aspect, a method for over-voltage protection is provided. The method includes connecting a first winding of a saturable reactor to a direct current (DC) source; connecting at least one phase of an alternating current (AC) electrical system to ground through a second winding of the saturable reactor; and controlling DC current flow from the DC source to the first winding of the saturable reactor in response to an over-voltage event, wherein energy is shunted to ground from the at least one phase of the alternating current electrical system through the second winding of the saturable reactor. |
