MiCOM Agile P441, P442 & P444
Distance Protection Relays
Part of the MiCOM P40 platform, the Agile P441, P442 and P444 numerical full scheme distance relays provide flexible, fast and reliable protection of transmission and sub-transmission lines. They include full scheme 6-zone distance, plus aided directional earth fault (DEF) and comprehensive backup protection for utility lines and cables at all voltage levels, particularly oriented towards transmission grids.
These distance protection systems are ideal for single circuit breaker application, single and/or 3-pole tripping, and includes a full suite of monitoring, control and recording capabilities plus fault locator, autoreclose and check synchronism.
Key features:
- Dual algorithm distance operation for maximum fault detection dependability
- Deploy in traditional CT/VT applications, or digital substation architectures with merging units and non-conventional instrument transformers using IEC 61850-9-2 process bus
- Distance to fault location assists dispatching of maintenance crews
- Full-scheme relay offers fast, discriminative response to double-circuit, cross-country and evolving faults
- No internal batteries in GE-branded models – removes a maintenance item and eases air-freight logistics
- NERC CIP cybersecurity including role-based access control (RBAC), RADIUS and SysLog
- Advanced binary inputs comply with the harshest norms for surge withstand, plus the ESI 48-4 EB2 standard. Spurious wiring pickup is eliminated without the use of interposing relays, external resistors or time delays. Battery/wiring faults, switching noise, and induction from long parallel circuits are tolerated without misoperation

What's New
Enhanced Ethernet board module with switchable Ethernet redundancy delivered in a single model. The new board module is supported on P442 and P444, also delivered along with the NERC CIP v6 Cybersecurity release, software 91.
It supports PRP, HSR and RSTP in one model, allowing a single P40 model to be used in any application requiring redundant Ethernet communications.
The new module is designed to handle high density traffic in the IEC 61850-8-1 network, with time latency halved. Larger architecture digital substations can also be supported, with up to 50 nodes now possible in IEC 62439 HSR rings.
Key Features & Benefits:
- Universal IRIG-B – Modulated and demodulated supported in the same model
- HSR Ring – Extended to 50 node support for larger substation architectures
- Fast performance, particularly in onerous applications such as where process bus GOOSE is used for tripping purposes
- NERC CIP cybersecurity including role-based access control (RBAC), RADIUS and SysLog
Overview
The Agile P441, P442 and P444 have a settable quadrilateral operating characteristic that offers consistent 0.85-1.1 cycle zone 1 operating time for general distance application. Customers have a choice of cost-effective built-in teleprotection with InterMiCOM, to implement permissive, blocking and intertripping schemes.
The IEC 61850 redundant Ethernet option offers RSTP and IEC 62439 PRP/HSR – with the HSR support extending for up to 50 nodes in a station bus ring.
Key benefits:
- Comprehensive communication options including IEC 61850 and redundant Ethernet ports
- IEC61850-9-2 interface option allows integration within digital substation process bus architectures
- Unparallelled speed, security and selectivity
- User customisable with graphical tools

Refurbishment Solutions – “If It\’s Blue Think to Renew”
GE\’s latest MiCOM P440 series models P441 to P444 inclusive offer an ideal path to refurbish an older installed base of MiCOM P440 relays. Whether those older products were initially sold as Alstom or AREVA-branded products, newer models retain pin-pin refurbishment capability. Advantageously, users can benefit from the advancements made in protection, control, communications, hardware and cybersecurity that have taken place in the intervening years. The new P40 retains form, fit and function compatibility but delivers the latest platform and software ready for today\’s environment, and for future-proofed application for the decades ahead.
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.
- Download converted files
- Test, return circuit to service with only minutes of downtime
