Product Description

The MiCOM P521 relay provides high-speed two-ended current differential unit protection of overhead lines and underground cables in applications such as ring mains and parallel feeders. The integration of many protection functions allows application to a wide range of power systems, providing both local and remote backup protection. Optimum phase selection is assured, as the scheme measures the currents entering and leaving the protected plant zone. Fast tripping results for an internal fault, with stability for any out-of-zone fault The signalling interface options support metallic, direct fibre optic and multiplexed digital links. As digital communication is used, long distances between scheme ends can be achieved, and the signalling channel is monitored continuously. Tripping uses a proven characteristic comparing differential current with through current. Phase differential elements of this type offer consistent detection of solid and resistive faults, with optimum faulted phase selection, tripping, and indication. A full range of back-up protection is integrated. This enhances the dependability of the protection, as hot-standby elements such as overcurrent can be brought into service whenever a signalling channel outage may occur. With latest upgrade, MiCOM P521 now can provide the optional Ethernet communication with 2 RJ45 interfaces.
