GE / Alstom MiCOM Agile P746 Centralized Busbar Differential Relay

GE MiCOM Agile P746 provides complete protection for MV and HV busbar configurations with up to 2 zones plus a check zone and up to 18 terminals. The MiCOM Agile P746 provides a centralized one box or three box architecture and is very simple to use, as it does not need to be deeply engineered and supports easy operation and maintenance of busbars.

The MiCOM Agile P746 protects voltage levels up to extra-high voltage busbar configurations. Proven techniques and dynamic topology processing algorithms offer a combination of security, speed and sensitivity, with simple configuration for centralized architectures.

Key benefits:
• Tripping time is independent of substation topology and number of terminals
• User-friendly software tools for scheme monitoring
• Built-in CT saturation proof breaker failure protection
• Compatible with both conventional and NCITs
• No internal batteries in GE-branded models – removes a maintenance item and eases air-freight logistics
• 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 mis-operation
• Harsh environment protection extends the life of the product

GE provides enhanced reliability through advanced protection for a wide range of bus protection applications. Our highly skilled technology teams understand bus bar principles and protection techniques, and use them to design, manufacture and support bus protection solutions that can be applied to a vast array of applications.
High magnitude fault currents require high speed operation of the bus bar protection to limit damage. However, this high speed clearing must be balanced against the need for security. Tripping incorrectly for an external fault may cause large outages and jeopardize power system stability. Learn more in our bus principles and protection guide.
