Generator protection relay Multilin 889

for transformersIECprogrammable

The Multilin 889 relay, a member of the Multilin 8 Series protective relay platform, has been designed for the protection, control, monitoring and management generators and in-zone transformers used in both industrial and utilities applications. The Multilin 889 provides advanced, high-speed protection, extensively customizable programmable logic, and flexible configuration capabilities, to maximize the operational performance and life of critical generators. Equipped with the latest in advanced communications, the Multilin 8 Series supports IEC 61850 Edition 2 ensuring simplified device integration and dual communication ports with IEC 62439/PRP, enabling users to achieve zero latency in communications for high reliability network architectures, ensuring complete asset monitoring and control. Key Benefits • - Enhanced generator protection algorithms provide sub-cycle differential protection, ensuring faster fault clearing times for reduced generator damage • - Dedicated generator monitoring and control functions providing mission critical operational data to enable a pro-active maintenance approach • - Additional overall generator-transformer differential (87O) providing additional back-up protection • - Advanced differential protection for both generator and in-zone transformer • - Industry standard cyber security tools such as AAA, Radius, RBAC and Syslog enabling NERC/CIP requirements • - Draw-out design simplifies testing and increases process uptime • - Optional Wi-Fi minimizes system configuration and facilitates safe relay programming and diagnostic retrieval
