Easergy Micom 740 Numerical Busbar Protection

MiCOM P740

Numerical BusbarProtection

Features

The MiCOM P740 numerical busbar protection scheme providescomplete protection for all voltage level, from low to extra/ultra high-voltagebusbar configurations.

One of the fastest and complete in its class, the MiCOM 740 provides secure andsensitive protection for all types of voltage busbar configurations. It iseasily adapted to any configuration and can operate with different types of CT.

Innovative configuration for centralized or distributedarchitecture

The MiCOM P740 ensures security, speed and sensitivity dueto its innovative configuration that includes CT saturation detection anddynamic topology processing algorithms. P740 protection, one of the fastestaround (13ms operating time) meets the strict requirements imposed byextra/ultra HV voltage transmission systems.

The MiCOM P740 busbar differential protection scheme can be engineered toprovide a centralized or distributed architecture. It also supports easy busbarmaintenance, operation and future expansion.

Fast, adaptable and easy to maintain

Typically operating at 11-15ms, MiCOM P740 enables fastfault trips. It can be adapted to any busbar configuration and operates withdifferent types of CT. A high-speed fiber optic cable, which eliminatesinsulation-related problems, can be used for communications between the CentralUnit and the Peripheral Units.

Fully communicant

With the availability of IEC61850-8-1 and IEC103 protocols,the P740 is easily integrated in any substation system.
