MiCOM P842

The MiCOM P842 Mesh Corner Reclose unit (MCU) provides a flexible, distributed scheme for delayed auto-reclose (DAR) and auto-isolation of a mesh bus station.

Using real-time, high-speed peer-peer communication facilities over the Ethernet, the MiCOM P842 provides a distributed scheme for delayed auto-reclose (DAR) and auto-isolation of a mesh bus station. Its flexibility means it can be used with different bus-bar arrangements.The MiCOM P842 Mesh Corner Reclose unit (MCU) provides a flexible, distributed scheme for delayed auto-reclose (DAR) and auto-isolation of a mesh bus station.

High-speed peer-peer communications

The MiCOM P842 uses high-speed peer-peer communication facilities over Ethernet, and provides for the automatic reclosure of circuit breakers. It also ensures automatic isolation of a persistently faulted plant and suppresses ferro-resonance, following a system fault.

The equipment is provided on the basis of one MCU per mesh corner. Although each MCU is an autonomous unit, inter-unit communication guarantees co-ordinated control of a complete mesh system.

Flexibility for easy commissioning and fault-finding

The MiCOM P842 ensures that only the faulted electrical plant is isolated for permanent faults. It provides flexibility for different bus-bar arrangements, carries out system checks, and suppresses ferro-resonance. MiCOM P842 is equipped with real time peer-peer communication, and allows easy commissioning and 'fault-finding'.
