It provides fast, highly selective railway catenary distance protection combined with the delta directional decision proven technique. The trip time is typically 0.7 to 1 cycle. Five zones of protection with quadrilateral characteristics allow versatile deployment as the main protection for all AC catenary/feeder systems. With independently settable right and left hand side resistive reaches for each zone the P44T suits routes hosting regenerative braking trains.

The MiCOM P54A/B/C/E range is designed for overhead line and cable applications up to 6 terminals, interfacing readily with the longitudinal (end-to-end) communications channel between line terminals. Previously, transmission and distribution circuits would have two or three ends only, whereas five or more ends are becoming common to connect renewable generation. All models are ready for protection topologies ranging from two to six terminals, whether those multi-terminals exist now, or are provisioned for connection in the future.

Accurate time synchronization is required to coordinate the actions of protective relays, generator controllers, distributed resources, power system controllers, energy storage, and microgrids. Every device must be synchronized to the same time source to ensure coordinated action. Traditional time synchronization methods have shortcomings, such as the separate analog copper wiring required for IRIG-B or the lower accuracy of SNTP/NTP over Ethernet networks.

The MultiSync™ 100 uses the IEEE Standard 1588-2008 for Precision Clock Synchronization Protocols used in Networked Measurement and Control Systems, as well as the C37.238-2011 IEEE Standard Profile used in Precision Time Protocols within Power System Applications. As a result, the MultiSync 100 provides highly accurate time synchronization, and allows for the gradual retirement of less accurate or more costly methods.
