Transformers Page
The Transformers page is used to match the unit with the configuration of the
generator voltage and current sensing transformers. To configure the Transformer
page, you must know the system wiring configuration. The settings that are
entered on the Transformers page must correspond to the actual wiring
configuration.
, for information on various wiring configurations.
See the VT and CT manufacturer data for assistance to enter the correct primary
and secondary voltages.
•
Generator VT Configuration - The generator VT configuration selections
are (1) single-phase, (2) two-transformer open delta, (3) three-wire Wye,
and (4) four-wire Wye. Use the two-transformer open delta setting for any
delta configuration. This parameter is stored in the tag
GenVT_Config
in
the configuration table.
•
Generator VT Primary Voltage - The primary voltage rating of the
generator voltage transformer is stored in tag
GenVT_Pri_V
in the
configuration table.
•
Generator VT Secondary Voltage - The secondary voltage rating of the
generator voltage transformer that is connected to V Gen A, V Gen B, and
V Gen C (and V Gen N for Wye configurations) of the CGCM-DLR unit.
This parameter is stored in tag
GenVT_Sec_V
in the configuration table.
