MiCOM Agile P84 - Multi-Functionnal Line Terminal Protection

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’s MiCOM P40 relays protects against corrosive gases such as H2S or SO2
No internal batteries in GE-branded models – removes a maintenance item and eases air-freight logistics
CyberSentryTM Advanced Security 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

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
CyberSentryTM Advanced Security including AAA, Radius, RBAC, and Syslog

MiCOM S1 Agile

Key benefits:

Powerful, free of charge, PC toolsuite
Optimum management of the installed base, structured as per the substation topology
Intuitive and versatile interface with file management facilities
Logical structure based on substation, voltage level and bay
Version control and cross-checking facilities for IED settings
Real-time measurement visualization – MiCOM S1 Agile extends to all MiCOM Agile IEDs - including P847 PMU and busbar schemes

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.

MiCOM S1 Agile software

Key features in the MiCOM S1 family:

GE’s integrated engineering tool that provides users with access to automation IED configuration and record data
Integrated configuration and monitoring features

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 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.
