The MiCOM Agile P44T is a multifunctional protection device, supplementing distance main protection with a host of backup protection, thermal protection, recording, control, measurement and monitoring features. It provides fast, highly selective railway catenary distance protection combined with the delta directional decision proven technique. The trip time is typically 0.7 to 1 cycle. Five zones of protection with quadrilateral characteristics allow versatile deployment as the main protection for all AC catenary/feeder systems.
Key Features & Benefits:
Many high speed, regional and urban rail networks worldwide are electrified. The exposed nature of overhead catenaries makes them fault-prone and protection devices are vital for selective tripping and isolation of any faulted section.
The MiCOM P44T Agile detects and trips faults in less than one power system cycle. This minimises the risk of downed conductors, making successful supply restoration more likely and ultimately minimising delays to trains.
Comprehensive backup protections and advanced communications make MiCOM P44T suitable for railway protection for classic or auto transformer-fed catenaries at 50 Hz and 60Hz.

GE Vernova\’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 GE VERNOVA 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.
The MiCOM P54A/B/C/E range is designed for overhead line and cable applications up to 6 terminals, interfacing readily with the longitudinal (end-to-end) communications channel between line terminals. Previously, transmission and distribution circuits would have two or three ends only, whereas five or more ends are becoming common to connect renewable generation. All models are ready for protection topologies ranging from two to six terminals, whether those multi-terminals exist now, or are provisioned for connection in the future.
For more than 100 years, electric power plants have mainly been large, utility-owned facilities, feeding distributed load based on unidirectional power flow. Over the past 20 years, smaller, independent power generation plants have been developed and distributed within electrical networks. The increasing number of Distributed Generation (DG) sites, and their increasing power ratings from kW to hundreds of MW, create new challenges for network planning and operation.
Circuits near the coast may be candidates for tee infeeds to evacuate renewable energy from onshore and offshore wind generation. A tee infeed to a nearby transmission line can be a more cost effective solution to connect the generation to the grid than building a new substation. This economy enables more Distributed Generation connections to penetrate the network helping to meet green energy connection targets and reduce greenhouse gas emissions.
Previously transmission and distribution circuits would have two or three ends only. However, five or more ends are becoming common because large Distributed Generation sites such as onshore or offshore windfarms and solar farms are being connected to the grid. As the power networks evolve to transport power in ever more complex ring and meshed networks, line/cable differential protection becomes increasingly attractive, with its inherent ability to address grading/selectivity challenges and is scalable for multi-terminal circuits able to accommodate many connections of distributed generation along the line. GE Vernova’s Electrification’ multi-ended current differential protection is now ready for any protection topology from two to six terminals, whether those multi-terminals exist now, or are provisioned for connection in the future.
Powerful graphical logic allows the user to customise the protection and control functions. The logic includes 32 timers, gates (OR, AND, MAJORITY) and set/reset latch functions, with the ability to invert the inputs and outputs and provide feedback.
The system is optimised to ensure that the protection outputs are not delayed by PSL operation. The programmable scheme logic is configured using the graphical S1 Agile software. The relay outputs may be configured as latching (lockout) or self-reset. All aspects of MiCOM P40 IED configuration are managed using the S1 Agile software.
All events, fault and disturbance records are time tagged to a resolution of 1 ms. An optional IRIG-B port is available for accurate time synchronisation.
Power System Measurements
Instantaneous and time integrated voltage, current and power measurements are provided. These may be viewed in primary, or secondary values.
Fault Location
A fault location algorithm provides distance to fault in miles, kilometres, ohms or percentage of the line length. The proven algorithm employed tolerates pre-fault loading and fault arc resistance.
Event Records
Up to 1024 time-tagged event records can be stored. An optional modulated or demodulated IRIG-B port is available for accurate time synchronisation.
fault Records
The last 15 fault records are stored.
Disturbance Records
The oscillography has 16 analogue channels, 64 digital and 1 time channel, all at a resolution of 48 samples/cycle.
To ensure compatibility with standard communications equipment, the MiCOM P54x Agile multi-ended line differential series is designed to work with IEEE C37.94TM. A direct fibre optic connection to a MUX is possible if the MUX is IEEE C37.94TM compliant.
In direct fibre optic applications, 1300 nm and 1550 nm channel options are available. The transmitters are designed with a large "optical budget" to support up to 150 km.
Dependable communications are essential for high-performance differential protection. Each active longitudinal channel is independently monitored and reports error statistics in line with guidance from ITU-T G.821.
Multi-ended line differential works in a ring connection, which provide comms redundancy. In the event of degraded communications, the ring communications channels will continue to provide protection, thus providing duplicated links via diverse communications paths.
Alternatively, back-up overcurrent elements can be switched into service, either as permanent parallel main protection, or temporary protection only during channel outages.
The wide range of communications options, including IEC 61850, provides interfacing with almost any type of substation automation system or SCADA system.
The following protocols are available:
P54x devices can be enhanced with an optional redundant Ethernet board. The redundancy is managed by the market's fastest recovery time protocols: IEC 62439-3 PRP and HSR allowing bumpless redundancy and RSTP, offering multi-vendor interoperability. The redundant Ethernet board supports either modulated or demodulated IRIG-B and the SNTP protocol for time synchronisation. The redundant Ethernet board also has a watchdog relay contact to alarm in case of a failure.
An additional second rear port can be ordered as an option, designed typically for dial-up modem access by protection engineers/operators when the main port is reserved for SCADA traffic. This port also offers the option of -103 communications when IEC 61850 is the chosen first port protocol.
P54A compact (40TE), economical line differential protection without VT inputs, offering non-directional backup protection.
P54B compact (40TE), economical line differential protection with directionalised back-up protection and inbuilt reclosing and check synchronism.
P54C transmission-class 1/3-pole tripping line differential protection with backup protection and inbuilt reclosing and check synchronism (built from today’s P543 hardware).
P54E transmission-class 1/3-pole tripping line differential protection with back-up protection and inbuilt reclosing and check synchronism with a large number of binary I/O for traditional hardwired schemes (built from P545 hardware).
