GE 889‑E‑P1‑P1‑B1‑L‑S‑S‑A‑L‑A‑M‑A‑P‑T‑A‑1E‑C‑N‑B‑N‑1 Generator Protection and Control

Product Description

GE Multilin 889 is an advanced generator protection, control & monitoring IED (Intelligent Electronic Device). Model: 889‑E‑P1‑P1‑B1‑L‑S‑S‑A‑L‑A‑M‑A‑P‑T‑A‑1E‑C‑N‑B‑N‑1. It belongs to GE Vernova Multilin 8‑series platform, featuring draw‑out pluggable hardware design with English language interface. Equipped with P1 current input module and B1 voltage input module, this unit integrates full‑set generator protection, measurement, disturbance recording and programmable logic functions. With high‑end communication hardware and mainstream power‑system protocols, it delivers primary and backup protection for generators and associated unit step‑up transformers, performing fault clearing, condition monitoring and synchronism control for power plant & industrial power station applicationsGE Vernova. It adopts FlexLogic programmable logic, provides comprehensive fault recording, disturbance report and asset monitoring functions. Supported by EnerVista configuration software for commissioning, setting management and post‑fault analysis.
