MiCOM Agile P746

Centralized Busbar Differential Relay

The 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

  • Harsh environment protection extends the life of the product




  • Typical operating time of 12 ms with high speed/high break contacts or 17 ms with standard contacts 

  • Phase segregated biased current differential high speed busbar protection 

  • Easy maintenance, operation and future expansion of the busbar supported

  • Deploy in ring-bus/mesh corners, single busbars, sectionalized busbars, and one per bus in breaker and a half topologies


Key benefits:

  • Use one box for schemes up to 6 feeders, and 3 boxes (one per phase) for larger schemes up to 18 terminals 

  • Interoperable with all classes of CT: IEEE, IEC, air-gapped, non-gapped, and CTs with moderate knee point voltage

  • 10 integrated function keys, tri-color LEDs, and graphical programmable logic permit the creation of comprehensive schemes, tailored to your needs 

  • IEC 61850 redundant Ethernet, supporting self healing ring, RSTP, dual homing, PRP or HSR


Remote HMI

P746 Remote HMI PC Application Software

Agile P746 remote PC HMI provides the following features:

  • P746 Remote HMI allows the user to display the MiCOM Agile P746 measured analogue quantities and DDB (digital data bus) status information dynamically via the user defined busbar topology

  • Available in English, French, German, Spanish, Chinese and Russian
