- MiCOM P841 Model A for Single Breaker Applications with 16 Inputs and 14 Outputs
- MiCOM P841 Model B for Two Breaker Applications with 24 Inputs and 32 Outputs
Single or Three-phase auto-reclosing applications
MiCOM P841 Model A can be applied as a stand-alone solution for Auto-reclose and Check synch functionality for feeders controlled by a single circuit breaker.
MiCOM P841 Model B can be applied as a stand-alone solution for Auto-reclose and Check synch functionality for Dual circuit breakers applications such as ring bus/mesh corner formations and the breaker-and-a-half configurations.
- 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.
