Numerical Busbar Protection

Schneider MiCOM P740 Numerical Busbar Protection

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 P740 is easily integrated in any substation system. Contractual warranty Period : 2 years  

Schneider MiCOM P64x Protection and control of transformers

Transformers are capital-intensive components of electrical systems. In order to ensure longer operation of the transformer, it would be good to eliminate all electrical and mechanical effects of loads, but this is impractical. Adaptable techniques to measure and warn (or react) in such cases and properly planned maintenance can help to apply preventive measures and thus avoid costly failures.

Schneider MiCOM P44x High-speed remote protection

The MiCOM P44x provides high-speed remote protection for all overhead and cable lines and a wide range of standard protection features. They come with a variety of serial and Ethernet communication protocols including IEC61850 and a multilingual HMI interface with English, French, German, Spanish, Russian and Chinese. Protection is further extended in the device using programmable circuit logic.

Schneider MiCOM P341 MiCOM P922G Login protection

The MiCOM P341 and P922G interconnection protection relays provide the protection required for devices connected in parallel with the main
