Part of the MiCOM P40 platform, the Agile P543 Line Differential Protection numerical relay and P544, P545 & P546 range of transmission-class protection relays provide comprehensive line protection for differential, subcycle distance and directional earth fault applications, with 1/3 pole tripping. This range of products is ideal for HV, EHV and UHV applications on lines and cables of any length.
The MiCOM Agile P543 Relay, P544, P545 & P546 range of transmission-class protection relays provide high speed current differential unit protection. They are designed for overhead line and cable applications, interfacing readily with the longitudinal (end-end) communications channel between line terminals. The interface options support direct fiber optic or multiplexed digital links.

Each of the models offer resident subcycle distance protection to complement the powerful suite of main and backup protection. Full scheme, five-zone distance protection is adopted from the class-leading MiCOMho MiCOM Agile P443. The product line becomes the standard in all HV, EHV and UHV line protection applications, duplicated where dual redundant main protection is demanded. Set any combination of differential, distance, overcurrent and reclosing, depending on the site needs. One universal relay type instead of two or more discrete models means reduced spares holding, less training, and lower cost.

The MiCOM Agile P544 and P546 are suitable for the complex installation and feeders controlled by two circuit breakers such as breaker-and-a-half configurations with dual breaker autoreclose logic schemes with synchrocheck for both breakers.

MiCOM Agile P14x feeder management relays provide an integrated solution for the complete protection, control and monitoring of overhead lines and underground cables, covering all distribution and transmission voltage levels. Providing all essential information to efficiently maintain complex power systems and their components, the P14x relay family is user-friendly and highly flexible, allowing application on any network.

The MiCOM Agile P14x is an advanced feeder management relay platform with overcurrent and earth fault protection, as well as autoreclose and a full suite of protection, control and monitoring functions. The relay can also be used as high impedance busbar with full scheme supervision. The platform also provides main or back-up protection for MV/HV, solidly earthed, impedance earthed, Petersen coil earthed and isolated neutral systems.

Key benefits:

• Full feeder management with efficient monitoring, control, recording and digital communications
• Supports all major digital control system protocols, easing integration into DCS, SCADA and engineering workstations
• Fast simple and reliable busbar protection: Numerical single-box solution with full scheme supervision

• New advanced opto 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.

Transformers are high capital assets in electrical power systems. Elimination of all electrical and mechanical stresses, although desirable to preserve transformer life, is impractical. Adaptive techniques to measure, alarm (or trip) and advise on cumulative service can help to schedule preventive maintenance before a costly failure occurs. Internal faults are a risk for all transformers, with short-circuits dissipating the highest localized energy. Unless cleared quickly, the possibility to rewind windings reduces and core damage may become irreparable.

GE's P642, P643 and P645 address all these issues, preserving service life and offering fast protection for transformer faults. A transient bias technique has been included, enhancing relay stability and CT requirements. Hosted on an advanced IED platform, the P64x incorporates differential, REF, thermal, and overfluxing protection, plus backup protection for uncleared external faults. Model variants cover two and three-winding transformers (including auto-transformers), with up to five sets of 3-phase CT inputs.

Key benefits:

• Backup and logging of through faults
