BUCHANAN, NY – Control room operators returned Indian Point Unit 3 to service this morning, generating electricity. Unit 3 had shut down automatically Monday night after its main electrical generator sensed an electrical disturbance in transmission lines that connect the plant to the external power grid.
The plant shut down safely, as designed, and operators performed as trained.
Workers replaced several electrical insulators on a high-voltage transmission line this week prior to returning Unit 3 to service. Insulators protect transmission lines and related electrical equipment from the high-voltage associated with each line.
Engineers will examine the replaced insulators over the next few days to help determine the cause of the electrical disturbance.
