Voltage and Current Sensing DECS-250
Configuration chapter of this manual. Typical generator phase-current sensing connections are shown in
Figure 5-2.

Cross-Current Compensation
Cross-current compensation (reactive differential) mode allows two or more paralleled generators to
share a common load. As shown in Figure 5-3, each generator is controlled by a DECS-250 using the
DECS-250 cross-current compensation input (terminals CCCT+ and CCCT–) and a dedicated, external
current transformer (CT) to sense generator current. The resistors shown in Figure 5-3 are used to set the
burden and may be adjusted to suit the application. Ensure that the power rating of the resistors is
adequate for the application.
