The Branch acts as the connection between Bus Bars to form a Network.  PowaMaster allows multiple Branch Sections to be cascaded to form a single Branch Connection between Bus Bars.  This Multi-Section Branch can thus have different conductors and Section Lengths.

The following properties of the Branch Section can be changed or viewed:

1.Name, Number and Description,

2.Conductor Type,

3.Section Length,

4.Derating Factor,

5.Operating Temperature,

6.Display Options.

To Place a Branch Section

With the mouse click on the Branch Button on the Toolbar or use the Branch command from the Network main menu. A Branch Section data dialog box will appear.  Enter all the relevant information and Click on a Bus Bar in the project from where the Branch is to be Connected.  Click on a second point in the Working Area to place a multi-Section Branch, OR select a second Bus Bar to connect to.

After you are done, Right Click on the Working Area to Reset the Command or Continue by placing more Branches.

Note:

1.Voltage Validation is done, ensuring that Illegal Voltage Connections will not be successful.

2.The Derating Factor allows the user to specify a maximum current carrying capacity for the conductor which is below the normal capacity allowed for that conductor size, e.g. If a derating factor of 0.9 is applied to a conductor of nominal capacity 250A, then PowaMaster will indicate that the conductor to be overloaded at currents of 225A and above. This factor allows the user to cater for conductors installed in unusual conditions, for example extreme heat or exposure to sun.

3.The Operating Temperature is not for derating but applies to the re-calculation of the conductor impedance as result of the difference between the temperature at which the manufacturer defined the conductor impedance and the temperature at which the conductor is operating. See Conductor Details
