Functions and performances of digital relays have improved with progress of various digital technologies, such as high-speed data sampling. On the other hand, it has been becoming difficult to keep service parts such as CPU and memory whose improvement or elimination cycle is considerably shorter than replacement cycle of protection systems. In such situation, a technical committee was established in ETRA in order to research future images of protection relays and so on. This paper summarizes a future vision of protection systems based on the investigation carried out by the committee.
