Overview
GE's Agile P34x generator protection solutions provide extensive functionality to meet all generator and generator - transformer applications, including differential protection for fast and selective tripping of phase and earth faults. All generator protection, control, monitoring, recording and communications components are housed within one box, and the solutions are accompanied by a comprehensive library of hardware options, protection and control functions to meet system requirements.
Key benefits:
- Extensive condition based monitoring features for generators and transformers
- Graphical programmable scheme logic eases protection scheme creation and avoids the need for external logic controllers
- Range of different protocols (MODBUS, DNP3, IEC 60870-5-103 and IEC 61850) are available
- IEC 61850 / DNP3.0 redundant Ethernet, supporting self healing ring, RSTP, dual homing, PRP or HSR
- Programmable curves for easy protection customization
Main characteristics:
- Sensitive rotor earth fault protection using low frequency injection method
- Harsh Environment Option to protect against corrosive gases such as H2S or SO2
- Generator and transformer thermal overload, transformer loss of life and through fault monitoring
- Extensive protection for large machines such as pole slipping and 100% stator earth fault protection (3rd harmonic and low frequency injection method)

Refurbishment Solutions
GE’s latest MiCOM P340 models offer a perfect functional match for LGPG relay from the heritage installed-base brands of GEC Measurements, GEC Alsthom, Alstom and Areva:
Refurbishment Solutions – “If It’s Blue Think to Renew”
GE’s latest MiCOM P340 series models P341 to P348 inclusive offer an ideal path to refurbish an older installed base of MiCOM P340 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 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
