The frequent failures and repairs of electrical transformers in a typical large electrical network leave behind lots of data that can prove to be very useful. In this paper, we investigate data structures used to trace backward old information that is normally missing from the latest version of the system database. The database involved is spatio-temporal in nature; it involves spatio-temporal attributes related to the various transformers on the network. This paper focuses on how to reconstruct the status of the network at any given time in the past.
