The XRF Series intelligent relay is a new type protection and control unit for switchgear in substations and distributions. It features the following functions:

-Protection

-Measurement

-Monitoring

-Control

-Communication

All the above functions listed are integrated in a programmable environment. The perfect flexibility and scalability of these new generation devices make it possible to integrate all the secondary functions in a unique device, leading to a smart and easy solution where the traditional scheme is ineffective and expensive.The XRF301P is the most recommended one in the whole XRF series, well suitable for primary protection or back-up protection for equipments and distribution lines of ungrounded system with rated voltage not higher than 66 kV. Usually, with XRF301P independently, all secondary protection and automation requirements of substation can be fulfilled, which is convenient for reducing device’s types and spare parts for projects.
