From the first version of CYPELEC Networks, when a two winding transformer and a three winding transformer are edited, users can configure and the select the tap changer with the aim to regulate the voltage in the buses connected by the transformer.
After the analysis process, it may occur that the selection of the tap changer may cause the voltage of the controlled bus to lie outside the maximum values specified in the panel. As of the 2018.c version, when this case arises, the program can emit a warning to tell users to carry out a check. This warning is emitted if the new check “Voltage limits in the selection of the transformer tap changer” is activated, which is done in “General settings” > “Line checks”.
