MiCOM P740
Numerical Busbar Protection Relay Scheme
Tính năng
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.
Innovative configuration for centralized or distributed architecture
MiCOM P740 ensures security, speed and sensitivity due to its innovative configuration that includes CT saturation detection and dynamic topology processing algorithms. MiCOM P740 protection, one of the fastest around (13ms operating time) meets the strict requirements imposed by extra/ultra HV voltage transmission systems.
MiCOM P740 busbar differential protection scheme can be engineered to provide a centralized or distributed architecture. It also supports easy busbar maintenance, operation and future expansion.
Fast, adaptable and easy to maintain
Typically operating at 11-15ms, MiCOM P740 enables fast fault trips. It can be adapted to any busbar configuration and operates with different types of CT. A high-speed fiber optic cable, which eliminates insulation-related problems, can be used for communications between the Central Unit and the Peripheral Units.
Fully communicant
With the availability of IEC61850-8-1 and IEC103 protocols, the MiCOM P740 is easily integrated in any substation system.
