> Subject: 12/22 Power Interruption
>
> On Wednesday 12/22/99 at 2:55pm, buildings on the normal 2400 volt loops
> experienced an unexpected two minute loss of power. The affected
> buildings
> were 1-17, 24,26,31,35,41,W4,W5,W7,W8,W15,W33,W51,W53.
>
> The power interruption came at the end of two days (Mon. and Wed.) of
> testing of the new 2000kW emergency diesel generator, switchgear and
> controls in the Central Utility Plant. We had transferred 2400v normal
> loads to the B bus on Monday morning to isolate them from disturbances
> related to emergency power testing. The unexpected two minute gap
> occurred
> while transferring circuits back to the normal configuration.
>
> We apologize for the disruptions this unexpected 2 minute interruption
> caused. The testing was completed on 12/22 and we anticipate smooth
> running
> through the Y2K weekend.
