The software enables you to calculate the required absorbed power or demand factor values for a static and miscellaneous electrical equipment item in your plant. The standard (default mode) for load data calculation is to enter an appropriate rated power and demand factor values and let the software calculate the absorbed power. Alternatively, you can also enter an appropriate demand factor and rated power values. In this case, Smart Electrical will calculate the absorbed power.

Therefore, the software does the following depending on your input on the Load Data tab of the Common Properties box:

  1. No values have been entered for the rated power, absorbed power, or demand factor.

    • Enter the rated power and absorbed power values to calculate the demand factor.

    • Enter the rated power and demand factor values to calculate the absorbed power.

  2. The three values (the rated power, absorbed power, and demand factor) have already been entered or calculated.

    • Changing the rated power recalculates the demand factor.

    • Changing the absorbed power recalculates the demand factor.

    • Changing the demand factor calculates the absorbed power.

To calculate the demand factor or absorbed power, do the following:

  1. Open the Common Properties box by right-clicking the load in the Electrical Index.

  2. Select the Load Data tab.

  3. Enter an appropriate rated power value.

    In order for the software to make the required calculation, you must select an appropriate rated power value either before or after you enter the demand factor or absorbed power value. The software will make the required calculation once the rated power and the second value have been entered.

  4. To calculate the Demand factor, type an appropriate Absorbed power value.

    OR

    To calculate the Absorbed power, type an appropriate Demand factor value.

  5. Select in another property or press the TAB key.
