GE Energy Announces Advanced Stator and Rotor Ground Fault Protection
for Generator ApplicationsPDF
GE’s Multilin™ Stator and Field Ground Protection modules provide advanced generator protection,
minimizing total generator life-cycle costs and increasing overall system availability.
Markham, Ontario—June 2, 2011 — GE Energy today announced the new Multilin Stator Ground Protection
module and the Field Ground Protection module that provide a complete generator monitoring,
protection and control solution when used in conjunction with the industry leading Multilin G60
generator protection relay. The advanced stator and field ground protection modules provide easy
system configuration, minimizes life-cycle costs and increases system uptime.
GE’s robust Multilin Stator Ground Protection module provides increased protection for the stator
winding of the generator by continuously monitoring the integrity of the stator windings during
stopped, starting and running conditions. This additional stator protection provides early detection
of winding degradation, limiting potentially critical failures, costly asset damage, and system
GE’s Multilin Field Ground Protection module provides the ability to quickly identify the fault location
in the field winding, minimizing operational downtime. The Multilin Field Ground Protection module
provides increased protection of the field winding and helps to prevent serious damage to the
generator, maximizing operational life span. In addition this device can be configured using either
single-point or double-point injection methods, providing increased application flexibility.
