According to the report, the underground network meets design, construction and reliability standards for the US electric utilities.
The report outlined recommended enhancements to underground equipment and engineering, operations and inspection practices.
The report recommendations include upgrading relays in the Morristown substation feeding the network to shorten restoration times when outages occur; completing a study of a secondary portion of the network to determine if additional fuses are needed to help protect against equipment damage; and replacing two electrical switches in the underground network.
The recommendations also include adding special guards at the Morristown substation to prevent animal-related power outages; conducting a pilot project to investigate available methods for securing manhole covers; and providing additional training for employees on vault inspections and data collection.
