Intelligent Line Defense That Stops Problems Before They Start.
MiCOM P14x offers high-speed, adaptable safeguardingfor both overhead transmission lines and underground cables — designed to operate reliably across different earthing arrangements, voltage ranges, and network layouts.
Along Feeders,
Slow Response Leads to Bigger Problems.
Older relays often misread direction, struggle with compensated networks, and fall behind in complex grids — causing poor coordination and incorrect trips.
Weak directional logic
Relays misjudge fault direction, leading to nuisance trips in ring networks.
No SEF sensitivity
Standard relays miss low-level sensitive earth faults in compensated grids.
Slow cold-load handling
Inability to distinguish inrush from faults causes avoidable startup delays.
Inaccurate voltage restraint
Lower reach on distant faults during voltage dips compromises safety.
Poor event insight
Zero digital recording makes grid-forensics and root-cause analysis a guessing game.
Meet MiCOM P14x
— Feeder control done right.
A powerful feeder protection platform for MV and HV lines. It brings multi-stage, fully directional phase and earth-fault protection, high-sensitivity SEF, and deep recording logic — adapting to every feeder grounding practice and grid condition.
Protection That Follows
Every Contour.
Direction, sensitivity and stability — engineered for complex line behaviour.
Three-layer earth-fault logic
Derived, measured and SEF — each with four stages for precision on every network type.
Voltage-dependent awareness
Voltage-controlled and restrained overcurrent boosts reach on distant faults safely.
REF for internal sensitivity
High- or low-impedance REF detects hidden faults missed by standard elements.
Negative-sequence intelligence
Detects unbalanced faults fast, even before current rises fully.
Thermal & overload security
Realistic multi-state models for cable, transformer and conductor protection.
Smarter feeder behaviour
Native cold load pickup and selective logic for accurate switching operations.
Six-stage phase protection
Shapeable directional IDMT or definite-time for any complex grading plan.
Built For Speed. Tuned For Selectivity.
Multi-stage logic, modular hardware and deep diagnostics
