The feeder protection relay REF615 can provide protection, control, measurement, and monitoring functions for power systems and industrial distribution networks. This relay was developed and designed on a new platform according to the IEC 61850 protocol. This enables the product to fundamentally support features such as interoperability and horizontal communication between on-site devices, without the need for additional communication modules. This relay can serve as the main protection for overhead and feeder lines in the distribution network, and can also serve as backup protection in systems that require separation of protection and control functions or require redundant protection. According to pre configuration, this relay can be used for networks with ungrounded neutral points, resistive grounding, compensatory grounding, and direct grounding, as well as for overhead lines and cable feeders. These applications are standard configurations in relays. Users can directly put it into operation after setting it up. The 615 series relays support multiple communication protocols: Modbus and IEC 61850 with GOOSE information.

DCS and TDCS are monitoring technologies that integrate 4C (Communication, Computer, Control, CRT) technology. A tree like topology system from top to bottom, where communication is the key. In the interrupt station, PID connects the computer with on-site instruments and control devices. It is a tree topology and parallel continuous link structure, with a large number of cables running parallel from relay stations to on-site instruments and meters. Analog signal, A/D-D/A, mixed with microprocessor. One instrument is connected to the I/O line by line and connected to the local area network LAN by the control station. DCS is a three-level structure consisting of control (engineer station), operation (operator station), and on-site instruments (on-site measurement and control station). The disadvantage is that the cost is high, and the products of each company cannot be interchanged or interoperated. The large DCS system is different from each other. Used for large-scale continuous process control, such as petrochemicals
