Generator Current Sensing
CGCM-DLR units provide 3-phase AC current sensing with provisions for 1 A
and 5 A nominal sensing ranges. The inputs for 3-phase current sensing are on
TB3. The ID (+) and ID (-) terminals are used for systems that are connected in a
cross-current compensation system.
Voltage and Current Sensing Connection Examples
The following examples depict typical connections of voltage (also called
potential) transformer (VTs) and current transformers (CTs) to the
CGCM-DLR unit for various bus and generator power system configurations.
These diagrams do not show all connections to the CGCM-DLR unit, nor are
they intended to show all possible wiring combinations. For assistance in wiring a
CGCM-DLR unit in a power system configuration that is not shown in this
manual, contact your local Allen-Bradley Distributor or Rockwell Automation
sales representative.
