DECS-250N configuration includes entry of the primary and secondary values for the transformers that
supply generator and bus sensing values to the DECS-250N. These configuration settings are illustrated
in Figure 150.
Generator PT
Voltage settings for the generator PT primary A and secondary B windings establish the nominal PT
voltages expected by the DECS-250N. ABC or ACB phase rotation C can be accommodated. Options for
the generator voltage sensing connections D include single-phase (across phases C and A) and three-
phase sensing using three-wire connections.
Generator CTs
Current settings for the generator CT primary E and secondary F windings establish the nominal CT current
values expected by the DECS-250N. DECS-250N sensing current can be obtained from a single phase or
all three generator phases
G .
Bus PT
Voltage settings for the bus PT primary H and secondary I windings establish the nominal bus PT voltages
expected by the DECS-250N. Options for the bus voltage sensing connections J include single-phase
(across phases A and C) and three-phase sensing using three-wire delta connections.
