Blow out the first ceiling panel, this will drop debris onto the floor panel. Run to the floor panel with the debris on it when the electrical field is moving away. While on the first panel, shoot out the 2nd ceiling panel and repeat. After you make it through the electrical field, there is a generator on the left side in an alcove, destroy it and it will shut down the electrical field.

Once you have stepped on the floor panels with the debris and taken out the panels above, move to the end of the field. Just to the left of this is the generator that will shut down the whole thing.
