BACKGROUND: Freeman Substation Circuit 1502 has been experiencing power outages and reliability issues due to the high failure rate of aged cables and protection issues involving obsolete underground distribution equipment. The circuit is served by HMPE insulated cable (high molecular weight polyethylene) and CIC type infrastructure (cable -in -conduit). This type of cable and infrastructure is responsible for 70% of Riverside Public Utilities' (RPU) electric system outages. Additional infrastructure serving Circuit 1502 includes obsolete submersible oil switches without fusing options that contribute to longer outages. With this type of equipment, In the event of an outage, the entire circuit trips as there is no other protection except at the Substation, and as a result, the entire circuit requires troubleshooting and manual restoration.
