Overview
The individual function-group types are stored in the “Auto transformer diff” function group folder. The “Auto transf. Diff.” function group contains the differential protection function and protection function relevant measured values. In the “Auto transf. auto side” function group all functions required for protection and supervision of an auto transformer auto side can be used. In the “Auto transf. comp. side” all the functions required for protection and supervision of an auto transformer compensation side can be used. In the “Auto transf. ground side” function group all the functions required for protection and supervision of an auto transformer ground side can be used. In the “Auto transf. neutral point” function group all the necessary functions for protection and for supervision of an auto transformer, which are related to a neutral-point current, are used.
For more detailed information on “Auto transformer diff” function group, refer to SIPROTEC 5 devices, V8.30 & higher manuals.
