Figure 71. DECS-250 Contact Outputs Status Indication Screen
Network Load Share
The screen shown in Figure 72 reports the error percent, reactive current, NLS average reactive current,
and number of generators online. The status indicators change from gray to green when a status is
active.
The Error percent is the deviation of the unit’s reactive current from the system average. The NLS
Average Reactive Current is the average of the reactive current of every unit in the system. Generators
Online is the number of units actively load sharing.
