MiCOM P341 secures tie-lines, interconnections, and critical network boundaries with fast distance protection, deep overcurrent logic, and precision frequency monitoring — built for grids where one unstable moment can ripple across regions.
Explore MoreOld relays miss swings, misjudge intertie conditions, lag on breaker failures, and can’t keep up with modern synchronism and frequency behavior. One wrong trip at the boundary — and the whole grid feels it.
The P341 brings proven distance protection, multi-stage overcurrent logic, frequency-based schemes, and robust breaker supervision into one modular relay. Optimised for interconnections, tie-lines, busbars, feeders, and transformers, it blends multi-zone distance protection, PSL automation, wide-frequency protections, and thermal dynamic line rating. Built for modern substations where stability, communication, and cyber security matter most.
From distance faults to frequency events — every boundary risk handled.
Multi-zone distance elements with adaptive characteristics for precise fault clearing.
Phase, earth, sensitive earth, and restricted earth fault stages with inverse and definite-time curves.
Power swing blocking, out-of-step tripping, and vector-shift detection for stable operation.
ROCOF, under/over-frequency, and voltage-vector shift for reliable intertie management.
Breaker failure, condition monitoring, and trip-circuit supervision ensure dependable clearing.
PSL for intertripping, permissive schemes, interlocking, and custom network logic.
Dynamic line rating, SOE, fault logs, disturbance waveforms, and thermal monitoring for informed operation.
Every module is designed for protection-critical performance.
Any interconnection. Any tie-line. Any complex protection boundary.
Perfect for high-value, high-impact points across power and industry.
From distance settings to swing curves — we configure P341 the way your grid runs.
