The Batch Load Association dialog enables you to balance load flow of a particular bus and associate multiple loads with a power distribution board (PDB) and a bus. Also, allows you to display the calculated consumption for the entire power distribution board or a particular bus belonging to the selected power distribution board. You can also assign a load to a particular phase or define a load as a three-phase load.
Power distribution board
Specifies the power distribution board with which you associate the loads.
Bus
Allows you to select a specific bus for which you want to perform load association.
Bus phases
(Available for the Loads tab only)
The check boxes in this group box allow you to filter the display of loads in the Associated loads data window according to their assigned phases. You define the bus phase labels in the bus Properties window.
Phase 1
Filters the Associated loads list and displays only the loads that are associated with phase 1.
Phase 2
Filters the Associated loads list and displays only the loads that are associated with phase 2.
Phase 3
Filters the Associated loads list and displays only the loads that are associated with phase 3.
All phases
Displays all the loads disregarding their phase association.
Create circuits and cells
(Available for the Loads tab only)
Create circuits
Enables you to automatically create a feeder circuit for all the loads that are not associated with circuits. This selection does not affect the associated loads that are already associated with feeder circuits. The software creates a circuit based on the last applied typical circuit. If no typical circuit is associated with the current load, the software creates a feeder circuit without any circuit components.
Create cells
Enables you to automatically create a cell where the software creates the feeder circuits for the associated loads.
Bus Tab
Allows you to specify the rated data for a selected bus.
Bus rated data
Line voltage
Allows you to specify a voltage associated with the bus line.
Maximum line current
Allows you to specify the maximum value of the line current.
Maximum active power
Allows you to specify the maximum kW value for the selected bus.
Maximum reactive power
Allows you to specify the maximum kVAr value for the selected bus.
Maximum apparent power
Allows you to specify the maximum kVA value for the selected bus.
Supply
Displays the supply (AC or DC) of the selected bus. You define these values in the Properties window of the current bus.
Number of phase
Displays the phase number for the selected bus. (Applies to AC current supply only.)
Overload percentage
Allows you to specify the overload percentage on the maximum line current. The line current determines the maximum allowed load on the bus. The overload percentage can have a value between 0 and 100. For example, if you specify a maximum line current of 100 A and an overload percentage value of 20, the software determines that the bus is overloaded if the total calculated line current exceeds 120 A. You can view overload data for a particular bus on the Total Bus Load Validation Dialog .
Spare load percentage
Allows you to specify a value between 0 and 100 for the spare capacity on the bus for future expansion. The software uses this value to calculate the available spare capacity of the bus.
Required power factor
Allows you to specify a power factor value that is required for the current bus. When calculating the electrical consumption for this bus, the software also calculates the power factor of a capacitor bank that is needed to correct the power factor of this bus. See Correcting Bus Power Factors Using Capacitor Banks.
Show Preferences
Displays the preference settings for the calculation method for All Feeder Load Summary Report and the settings for the inclusion of coupled buses in All Feeder Load Summary Report.
Manage Operating Cases
Opens the Manage Operating Cases dialog where you can add, edit, or delete property values specific to various plant operating cases that exist for the current plant item.
