Product Description

889 Generator Protection System

The Multilin 889 relay, a member of the Multilin 8 Seriesprotective relay platform, has been designed for the protection, control,monitoring and management generators and in-zone transformers used in bothindustrial and utilities applications.

The Multilin 889 provides advanced, high-speed protection,extensively customizable programmable logic, and flexible configurationcapabilities, to maximize the operational performance and life of criticalgenerators.

Equipped with the latest in advanced communications, theMultilin 8 Series supports IEC 61850 Edition 2 ensuring simplified deviceintegration and dual communication ports with IEC 62439/PRP, enabling users toachieve zero latency in communications for high reliability networkarchitectures, 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

To simplify the migration and upgrade from an existing SR489 protection relays, retrofit kits have been developed which significantlysimplify the upgrade process.
