The logic capabilities of the MiCOM P841 products are extremely versatile, for instance managing leader-follower reclosing schemes in case of dual breaker applications.
Transmission-class circuit breaker failure protection for one or two breakers. The breaker failure protection may be initiated from internal protection within the P841, and also from external devices.
Single pole and three-pole breaker operation is supported, with independent supervision & condition monitoring statistics for each pole
Trip circuit supervision, control, and interlocking schemes can be designed in graphical support software.
Ancillary applications include use of the P841 for binary I/O concentration, disturbance recording, or as a gateway to SCADA protocols and IEC 61850
Multiple protection elements are provided, such as directional overcurrent, earth fault, voltage and frequency. This allows P841 to be deployed as a back-up IED in transmission applications, or as the Main 2 protection solution for sub-transmission systems.
