Narrative:
We were in cruise; level at FL230; when we were issued a descent to 17;000 ft. Just after that call was received; several things happened. First; I noticed that the captain's eadi; ehsi; and the TCAS screens all went blank. I received a red 'FD' and 'cross side data' flag on my eadi. Those events happened at almost the same time. Within a second; the screens came back on; and the flags went away. There was a master caution light illuminated now; and it was for an electric look-up light. On the overhead panel; the 'bus tie' connect and 'left generator' warning lights were illuminated. I called for the electrical; non-normal checklist. The captain worked through the checklist; and after the checklist was finished which lead us to declare an emergency; she then contacted dispatch and company while I flew the aircraft. We continued the arrival as filed. Later; closer to ZZZ passing 5;400 ft; ATC asked us 'were you assigned 6;000 ft?' to which we replied; 'no; we were assigned 4;000 ft.' the rest of the flight continued without incident.
