Operators must have a relay lifecycle strategy to ensure device health and power system reliability. If you have an earlier generation UR, this paper guides you through a strategy and demonstrates how the UR minimizes typical device upgrade costs.

This paper will discuss the evolution of bus protection, focusing on distributed bus protection schemes and five key considerations in implementing IEC 61850 process bus distributed bus protection schemes in modern power systems.
