P84 MiCOM 5th Generation
Multi-Functional Line Terminal Protection
The P84, part of the MiCOM P40 Agile 5th Generation family, is a multi-functional line terminal Protection that delivers high performance processing and a graphical HMI as standard. It is ideal for HV, EHV and UHV applications on lines and cables for 1 or 2 breaker applications with patented adaptive auto-reclose functionality.
Key Benefits:
- Full suite of monitoring, control and recording capabilities plus fault locator.
- Multi-shot autoreclosure with check synchronism - adaptive technology to detect fault arc extinction and accelerate the dead time or drive to lockout for persistent faults
- Transmission-class circuit breaker failure protection (< 3/4 of a cycle)
- Harsh environment coating as standard for all GE Vernova’s MiCOM P40 relays protects against corrosive gases such as H2S or SO2
- No internal batteries in GE Vernova-branded models – removes a maintenance item and eases airfreight logistics
- Advanced Cybersecurity including AAA, Radius, RBAC, and Syslog
- IEC 61850 9-2LE Process Bus capability with PRP in all models
- Secure Data vault with 5000 events, 100 Fault records and over 1000s of Oscillography
- Binary inputs ESI48-4 EB2 compliant
- Advanced IEC 61850 Edition 2.1 implementation
- Dedicated RJ45 Ethernet port for engineering access by protection engineers/operators

What's New
Overview
Transmission and distribution systems are essential for the safe, sure routing of power from generation sources to consumers. However, exposed overhead lines transporting power are by nature sometimes vulnerable and prone to fault. In the case of a faulty circuit, the MiCOM range provides speedy protection to trip and isolate it, thereby preventing further damage. Each relay model contains a complete suite of backup protection elements covering all current, voltage and frequency applications. This permits simplified application and spares holdings, because the relay can be adopted as the standard protection platform.
The MiCOM P84 is suitable for feeders controlled by a single circuit breaker and for complex installations where feeders are controlled by two circuit breakers such as ring bus/mesh corner formations and the breaker-and-a-half configurations.
Key Benefits
- Extremely versatile, e.g. managing leader-follower reclosing schemes in the event of dual breaker application
- Multi-shot 1/3pole & 3pole autoreclosure with check synchronism - adaptive technology to detect fault arc extinction and accelerate the dead time or drive to lockout for persistent faults. Improves system stability whilst reducing OPEX.
- Fast CB failure resetting (<3/4 cycle).
- Same heritage as the class leading MiCOMho P44 and MiCOM P54 family of products.
Main characteristics:
- Comprehensive communication options including IEC 61850 Edition 2
- IEC 61850 redundant Ethernet protocols - RSTP, PRP or HSR
- IEC 61850 9-2LE redundant PRP Process bus protocol
- Advanced Cybersecurity including AAA, Radius, RBAC, and Syslog

Engineering Tool Suite
S1 Agile is the truly universal PC tool for MiCOM Agile relay, assemble all tools in a palette for simple entry, with intuitive navigation via fewer mouse-clicks. No-longer are separate tools required for redundant Ethernet configuration, phasor measurement unit commissioning, busbar scheme operational dashboards, programmable curve profiles or automatic disturbance record extraction – applications are embedded. MiCOM S1 Agile supports all existing MiCOM, K-Series and Modulex, including a utility for automatic conversion of setting files from previous generations of numerical relays like K-series and MiCOM P20 to the latest P40 Agile models.
To move to the future, with no loss of functionality, no loss of device support, and full compatibility with your installed base and system architecture – request a copy of S1 Agile with the contact form link below.
Key features in the MiCOM S1 family:
- GE Vernova’s integrated engineering tool that provides users with access to automation IED configuration and record data
- Integrated configuration and monitoring features
- Send and extract setting files
- Single Line Diagram creation with inbuilt editor
- Event and disturbance record extraction and analysis

Refurbishment Solutions
GE’s latest P84 MiCOM 5th Generation transmission models offer a perfect functional match to our “mho” family of distance relays, from the heritage installed-base brands Alstom and Areva. The protection pedigree is maintained, optimised and advanced:
MiCOM P841A/B Relay Replacement:
- Form, fit and functional compatibility – the P84 fits in the same panel or rack space and offers the same features and Protection performance.
- The same S1 Agile software supports the new MiCOM relay and the legacy P841A/B
Pin-Pin Upgrade Methodology:
- Take the order code (CORTEC) of the older relay being removed, typically a blue case relay
- Translate to today’s latest GE Vernova MiCOM model, adding Ethernet options if required
- Order the new P40 relay
- Extract settings and logic, use S1 Agile toolsuite to convert settings
- Detach the terminal blocks from old relay, leaving wiring attached / detach terminal blocks from the new.
- Carefully examine the terminal blocks to see that no physical damage has occurred since installation.
- Mount new relay. Old relay blocks fit straight onto the new relay - safer, less wiring to reconnect.
- It is recommended to apply rated current and voltage to the relay CT/VT inputs during secondary injection testing to check the continuity of the CT/VT terminal block connections to the relay.
- Download converted files
- Test, return circuit to service with only minutes of downtime
