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.
