DSR deployment converts the existing transmission system to a smart asset that can bring extensive monitoring capability, regulate power flow and effectively shift overloads to underused portions of the network. Each DSR contains a high-performance control, sensing and communications module that enables exchanging messages with adjacent DSRs and a local network interface bridge (NIB). Secure communication takes place between the NIB, which acts as a local intelligent control agent, over a backhaul Internet-protocol connection to the smart wire system manager (SWSM), which manages the NIBs and their assigned group of DSRs.

The SWSM provides central management for configuring the NIBs and DSRs, operating the DSRs and monitoring status, field data, device health and data archiving. Each DSR acts as a distributed sensor that provides line current, harmonics, temperature, fault indication, fault current with time and location, ambient temperature, vibration and sag angle. Each DSR also has a built-in fault detector that, when detecting a line fault, removes a DSR that is in injection mode and places it into monitoring mode until the fault is no longer detected. This allows for DSRs to be deployed without affecting line-protection settings.
