Break Bus Symbols into Sections - Intergraph Smart Electrical - Help - Hexagon

Prior to generating an SLD for a power distribution board or when regenerating an existing SLD for a PDB, you can instruct the software to break the bus symbols on the drawing into bus sections. This way, you can manage the number of feeder circuits that are connected under each bus section on your SLD and make the labels of the connected electrical items more legible.

1. On the Single Line Diagram Options dialog, select the Buses tab.

   This dialog opens automatically if you are generating a new SLD for a power distribution board. If you are regenerating an existing drawing, select Tools > Drawing Options.

2. Under Display options, select the Force bus breaks check box.

   When generating your SLD, the software breaks the bus symbols on the drawing into sections and places them in rows underneath each other. The software displays the electrical items on the buses over several rows according to the bus breaks. You can move the individual bus sections and place them on the drawing as you require. Also, you can move the incomer and feeder circuits from one bus section to another on the same bus. Clear this check box to instruct the software not to break the bus symbols into sections and display of all the circuits on the same row.

3. Under Maximum number of feeders per bus section to display, type the maximum number of feeders to allow on each row of the drawing.

   The software forces bus breaks wherever the number of feeders on the bus exceeds the specified maximum.

   

   • When forcing bus breaks, the software places the maximum number of feeder circuits on the first bus section according to the value that you enter. Then, the software places the rest of the feeders on the next section. For example, if you enter 3 as the maximum number of feeders per bus section and there are 5 feeders on that bus, the software will place 3 feeders on the first section and the other 2 feeders on the second bus section.

   • All the incomer circuits for each bus are drawn on the first bus section only.

   • You can move the incomer and feeder circuits from one bus section to another bus section on the same bus as you require. Click an incomer or a feeder circuit symbol to select it and then drag its connection point on the bus to another bus section of the same bus.

   • Where two buses are connected by a coupler-riser, the software does not force a bus break across the connection. Instead, the software draws the first bus section and then counts the feeders from the riser on the second bus section before forcing the break.See Bus Break Example. Note that you can move coupler and riser circuits to another section of the same bus just like any other circuit.

4. Select the Use multiple sheets if you want to display each row of items on a separate drawing sheet. When this option is selected, the software uses off-page connector symbols with appropriate labels to show the continuation between adjacent sheets. Clear to display all the items on a single drawing sheet. When cleared, the software uses row break symbols to show the continuation between adjacent rows. Note that this option becomes available after selecting Force bus breaks.

5. Select another tab or Generate as required.
