The function changes the voltage level (subtype) for objects in a traced network. Select a start object in the network and then select the voltage level that the traced objects should be changed to. The voltage levels that can be selected depend on configuration and on the voltage level of the selected start object.

The trace follows connected objects with the same current voltage level and stops when it reaches another voltage level.

The function also checks subtype-dependent codelist fields. If a codelist field has a value that cannot be matched by code text in the target voltage level, the function shows this in the result dialog and asks whether the change should be forced. If the change is forced, those listed field values are set to empty/null and must be documented manually afterwards.

 

Prerequsites

•The network that should be changed should be disconnected from the rest of the network. The trace stops when it reaches another voltage level. We recommend using the function on smaller parts to minimize time and manual follow-up work.

•All objects that will be included in the change must be unlocked. This includes traced objects and, if selected, cable pillars/stations. If at least one object is locked, the function does not perform the change and shows an error message.

•Undo/Redo does not work for this function. To revert the result, you need to revert the whole changeset by using File > Empty changeset, before the changes are posted.

•Before forcing a change, make sure that subtype-dependent codelists for the target voltage level contain corresponding values with the same code text. If you force the change when no corresponding value exists, the listed field values are set to empty/null and must be set manually afterwards.

 

Perform the voltage change

1.Select Tools > Change voltage for traced network.

2.Select an object in the part of the network that should be traced. A dialog opens.

3.In the drop-down list, select the voltage level (subtype) that the traced network should be changed to. Only allowed target voltage levels are shown.

4.The checkbox Change also on cable pillar/station is selected by default. Leave it selected if the function should also change the voltage level (subtype) for the cable pillar/station parent objects that belong to the traced network. Clear it if only the traced network objects should be changed.

5.Press OK. The function traces the network and opens a result dialog.

6.If one or more subtype-dependent codelist values cannot be matched in the new voltage level, the result dialog lists the affected objects and fields as Non-changeable with the message Could not find suitable replacement value. A confirmation dialog asks whether to perform a forced subtype change:

oYes - The function performs the voltage change anyway. The listed field values that have no matching codelist value in the new voltage level are set to empty/null. These fields must be reviewed and set manually afterwards.

oNo - The voltage level does not change. The results dialog remains open and shows which objects and fields could not be changed.
