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