Viewing Medium Voltage Cables

5.6 Viewing Medium Voltage Cables

After entering this tool, you can view the cable paths of each grid connection point, as well as cable section, and cable length. It can automatically calculate or manually edit the connection relationship.

Note: To prevent automatic changes in manually edited connection relationships, the connection relationship of each grid connection point is automatically calculated only once after entering the cable viewing tool. When modifying the wiring, cable path, etc., if there is a prompt in the upper left corner indicating that there are devices without connection relationships, you can manually edit or right-click to recalculate the connection relationships.

5.6.1 Before entering a single grid connection point

After entering the tool, move the mouse up and down on the legend of the grid connection point in the upper left corner (hover the mouse without clicking the left button) to display the path of the corresponding medium voltage grid connection point.

When the legend in the upper left corner is missing the text "connected", as shown in the left figure below, the main possible reasons for the 2 # grid connection point are as follows:

1) The transformer (or middle point) belonging to the grid connection point is not connected to the medium voltage path. After entering the grid connection point, as shown in the figure below, there is no connection path for the 6# transformer.

2) The connection relationship is incomplete. After entering the grid connection point, as shown in the figure on the right below, the 10# transformer has no connection relationship.

3) It is also possible that both of the above situations exist.

Before entering a single grid connection point, right-click to bring up the menu:

The main functions are as follows:

• Modify, lock and re-tag the grid connection point/MV point

• Modify the 'Max distance from trans.to MV trench' .

• Recalculate/Clear Connection Relationship: After modifying the wiring and path, this function can be used to recalculate the connection relationship.

• Switch to other tools.

5.6.2 After entering a single grid connection point

You can enter a single grid connection point by clicking on the grid connection point legend / grid connection point entity / power block belonging to the grid connection point.

By clicking on the legend/transformer entity/power block, you can view the cable path from the transformer to the next device. The SketchUp interface will display the length, section, and number of cables in the lower left corner.

Right click to bring up the menu:

The main functions are as follows:

• View and edit connection relationships:

1) Move the mouse to the connecting line (dark blue), and the connecting line will turn bright. Right click to clear the connection between the two.

2) Click on two devices or power blocks in sequence with the mouse to establish a connection relationship.

3) The connection relationship is a tree like structure based on the connection point as the root, and cannot be circular.
