SIGMA Site Load Correction
Maintain predetermined load on a genset to alleviate the effects of light loading.
The SIGMA site load correction (SLC) will automatically maintain a required level of loading on the generating set. Element groups in the load bank are controlled by internal contactors, which are in turn controlled by the SIGMA load share control. The system includes a three-phase power transducer that detects the site load. When the site load decreases, the load provided by the load bank will increase.
