PRODUCT INFORMATION
Product Overview
The General Electric UR 8LH Multilin CT/VT Module provides secondary instrumentation scaling for Universal Relay platforms. This hardware option equips compatible protection relays with secondary transformer acquisition channels. It supplies four current transformer and four voltage transformer input channels with diagnostic monitoring. The module allows field engineers to upgrade relay capabilities or replace existing instrumentation cards. It interfaces high-voltage network signals with relay digital processors.
Internal transformers scale down high line currents and potentials into manageable secondary measurement values. Protection algorithms determine ratio conversions to detect power system abnormalities accurately. Built-in diagnostic functions verify analog signal integrity continuously across each analog channel. Operational data displays directly on the front panel liquid-crystal display. Engineers can also monitor parameters remotely through EnerVista UR software.
