Simple configuration for centralized architecture

The 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.

Fast, secure and easy to use

With a typical operating time of 12 ms with High Break High Speed contact option or 17 ms with standard contacts, the P746 protection is one of the fastest in its class.
Moreover, the trips can be synchronous or sequential.
The dynamically changing substation topology of the busbar is displayed on any PC with the substation real time dynamic monitoring tool.

Fully communicant

Fully communicant with IEC61850-8.1, Courier, DNP3.0, Modbus and IEC103 protocols, the P746 is easily integrated in any substation system.
