Schneider Electric Easergy MiCOM P441 High Performance Distance Protection Relay

Schneider Electric Easergy MiCOM P441 High Performance Distance Protection Relay is designed to provide fast and dependable protection for transmission and sub-transmission lines. It combines high-speed distance protection with backup protection, monitoring and control functions, making it suitable for overhead lines and underground cable networks across medium, high and extra-high voltage systems.

The MiCOM P441 provides five-zone distance protection together with directional earth fault protection and comprehensive backup functions. It is suitable for single circuit breaker applications and supports both single-pole and three-pole tripping. Built-in fault location, auto-reclose and check synchronism functions help improve fault restoration time while reducing network interruptions.

The relay integrates easily with modern digital substations through IEC 61850 communication and process bus support. Advanced teleprotection options, event recording and Ethernet redundancy make the MiCOM P441 a practical solution for utilities and industrial power systems that require reliable transmission line protection.
