Reliable Grid Link Security Built to Act Without Hesitation.
MiCOM P341 safeguards interconnecting lines and vital system interfacesusing rapid distance protection, advanced overcurrent functionality, and accurate frequency supervision.
Where Networks Connect,
Delay Can Lead to System Instability.
Traditional relays often fail to detect power swings accurately, struggle with intertie evaluation, and provide limited synchronism supervision. A single incorrect trip at a system boundary can disrupt stability across the entire network.
Slow fault detection
At the grid edge, a few milliseconds delay in clearing a fault triggers regional instability.
Weak swing stability
Standard relays misjudge power swings as faults, leading to unnecessary intertie trips.
Poor breaker oversight
Lack of condition monitoring and failure logic risks grid hardware damage during events.
Limited frequency logic
Relays cannot track ROCOF or vector shifts accurately during inter-regional transfers.
No redundancy paths
Single-point communication failure isolates the protection unit from central SCADA systems.
Meet MiCOM P341
— Interconnection protection with authority.
P341 blends multi-zone distance protection, PSL automation, and wide-frequency logic into one modular relay. Optimised for tie-lines and boundaries where stability, communication, and cyber security matter most.
