Alstom Launches PRP Redundancy in its MiCOM Relays, Bay Controller & Switches

Alstom's MiCOM P40 relays, C264 bay controller, and MiCOM H switches are now available to order with an IEC 62439 PRP option.  PRP (Parallel Redundancy Protocol) offers a vendor-interoperable solution to implement redundant star Ethernet architectures. 

PRP is particularly useful in deploying IEC 61850 station bus communication, as a new alternative to previous redundant communications standards such as RSTP. 

Marrying the two IEC standards together, the new developments progress your substation system engineering in line with advancements in digital technology.  PRP offers instantaneous communication recovery, compared to 25ms or more healing time for RSTP.

 

Power. Flexible. Easergy.
