Schneider Electric Easergy MiCOM P445 Numerical High Performance Distance Protection Relay

Schneider Electric Easergy MiCOM P445 Numerical High Performance Distance Protection Relay is designed to provide fast, accurate and dependable protection for overhead transmission lines and underground cable networks. It combines distance protection, control, monitoring and communication functions in a single relay, making it suitable for high-voltage and extra-high-voltage transmission systems where fast fault clearance is essential.

The MiCOM P445 offers a comprehensive range of protection functions with support for both quadrilateral and mho distance characteristics. It also includes power swing detection and blocking, multishot auto-reclose, check synchronism and programmable scheme logic, allowing the relay to be adapted to different transmission network requirements. Its high-speed operating performance helps minimise fault clearing time and improve overall network reliability.

The relay integrates easily with modern digital substations through IEC 61850 communication, Ethernet redundancy and advanced teleprotection features. With flexible communication options, detailed event recording and enhanced cybersecurity, the MiCOM P445 is well suited for both new installations and transmission system upgrades.
