GE / Alstom MiCOM Agile P747 Centralized Busbar Differential Relay

GE MiCOM Agile P747 provides complete protection for voltage levels up to extra high voltage busbar configurations with a centralized 3-box architecture. The MiCOM Agile P747 can accommodate up to 4 zones plus check zone and protect up to 18 terminals. The MiCOM Agile P747 Is particularly useful in double busbar with double bus coupler applications and allows a high number of opto inputs, relay outputs, and virtual inputs and outputs to manage the complete substation scheme.

The MiCOM Agile P747 also incorporates enhanced circuit breaker failure logic with additional protection functions such as dead zone and overcurrent. In addition, the MiCOM Agile P747 provides a wide range of measurement, monitoring, post fault analysis and self-diagnostic features. Powerful programmable scheme logic, trip circuit supervision, fully customizable menu texts, multi-level password protection, on-line measurements and plant status monitoring are all included. MiCOM Agile P747 employs an innovative external fault detection algorithm to ensure stability when CTs become saturated.

Key benefits:
• Tripping time is independent of substation topology and number of feeders
• User-friendly software tools for scheme monitoring
• Built-in CT saturation proof breaker failure protection
• 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.
