Siemens SIPROTEC 5 User Manual

The following figures show the setting sequence in the Primary edit mode. Set the transformer data in the
Power-system data in the Measuring point V 3ph tab. In the example, the current transformer has a trans-
formation ratio of 400 kV/100 V.

Figure 3-44 Setting Sheet: Transformer data
You set the rated current and rated voltage in the 3-phase voltage/current function group, in the General
function block (see the following figure). Rated current and rated voltage are the reference parameters for the
percent setting.
