P54 MiCOM 5th Generation

Line Differential and Distance Protection

The P54, part of the MiCOM P40 Agile 5th Generation family,

is a line differential and distance Protection that delivers high performance processing

and a graphical HMI as standard.

A cost-effective range of transmission/sub-transmission class protection relays

providing comprehensive line differential protection for up-to 3 line ends,

with in-built sub cycle transmission class distance and directional earth fault protection.

This range of products is ideal for HV, EHV and UHV applications on lines and

cables for 1 or 2 breaker applications with patented adaptive auto-reclose functionality.

checks and interlocking capabilities

Key features:

Differential protection applicable to lines and cables, long or short, strong and weak infeeds
Multi-shot autoreclosure with check synchronism - adaptive technology to detect fault arc extinction and accelerate the dead time or drive to lockout for persistent faults
Serial and Ethernet concurrent protocols, switchable by settings
Advanced IEC 61850 Edition 2 implementation
CyberSentry™ Advanced Security including AAA, RADIUS, RBAC, and Syslog
With fast start up time of less than 10s, resulting in protection, control and communications without the need to wait
