Provides information about the load properties based on the output power requirements.

Rated apparent power

Shows the quantity of electrical power in kVA that represents the vector sum of the active and reactive power.

Power factor

Enter the ratio of active power to apparent power at 100% of the rated power and at the demand point. The power factor can have a value between 0 and 1.

Rated active power

Shows the maximum quantity of electrical power in kW that the generator needs to supply to the network.

Supply

Select the type of supply that the generator produces: alternating current (AC) or direct current (DC).

Number of phases

Select the number of phases in the generator output. You can select 1 or 3 phases. This property applies for an AC supply only.

Frequency (Hz)

Select the operating frequency of the generator. You can define and customize the available frequencies in the Data Dictionary Manager. This property applies for an AC output only.

Rated voltage

Select the voltage which the generator is designed to supply. This quantity usually appears on the generator nameplate. You can define and customize the available rated voltages in the Data Dictionary Manager.

Efficiency

Enter the ratio of power output to power input under the conditions of 50%, 75%, and 100% of the rated power. The efficiency can have a value between 0 and 1.

Neutral Earthing

Allows you to select a child power cable or busway to create a neutral earthing connection branch under the current generator in the Electrical Engineer. In an SLD, the software will create an independent branch connected to a non-power connection point of the generator. See Define a Neutral Earthing Connection for Generators.

Number of poles

Select the number of poles for the generator. For example, you can select 2 or 4 poles. You can define and customize the available number of poles in the Data Dictionary Manager.

Synchronous speed

Displays the maximum theoretical rate of rotation of a machine shaft, in revolutions per minute (rpm), assuming no energy losses due to the magnetic field, pole architecture, and so forth.

Override FLA calculation

Select the required option to determine whether the software uses a calculated or manually typed full load current value. If you select Calculated, the software calculates the full load current value based on values you enter on this tab; the calculated value overwrites any value that you previously entered manually. Selecting Manual enables data entry in the Full load current box, with the last calculated full load current as the starting value.

Full load current (FLA)

The electrical current, in amperes, that the generator supplies when operating at maximum power. The full load current usually appears on the nameplate of the generator. You can select Calculated or Manual from the Override FLA calculation list to determine whether the software calculates this value or whether you enter a value manually.

Control mode

Allows you to select the generator control mode that determines how the generator behaves under different load conditions; for example, Isochronous, Droop, Isochronous/Droop. The software uses this description in filters and reports. You can define and customize control modes in the Data Dictionary Manager.
