Numerical Busbar Protection Relay Scheme (Centralized)
Easergy™ MiCOM P746 numerical busbar protection provides centralized complete protection for all voltages level up to extra high voltage busbar configurations.
Models available:
MiCOM P746
Simple configuration for centralized architecture. The Easergy MiCOM P746 differential busbar protection provides a centralized one box or three boxes architecture and is very simple to use.
It does not need to be deeply engineered and supports easy operation and maintenance of the busbar.
Numerical Busbar Protection Relay Scheme (Distributed)
The Easergy MiCOM P740 numerical busbar protection scheme provides scalable and complete protection for all voltage levels, from low to extra or ultra high-voltage busbar configurations.
Models available:
MiCOM 741
MiCOM 742
MiCOM 743
Easergy MiCOM P740 is one of the fastest and complete in its class, providing secure and sensitive protection for all types of voltage busbar configurations. It is easily adapted to any configuration and can operate with different types of CT.
