2-2 N60 Network Stability and Synchrophasor Measurement System GE Multilin
2.1 INTRODUCTION 2 PRODUCT DESCRIPTION
2
The N60 IEDs use flash memory technology that allows field upgrading as new features are added.
The following Single Line Diagram illustrates the relay functionality using ANSI (American National Standards Institute)
device numbers.
