Provides information about the converting equipment properties based on the output power requirements.

Rated power

Allows you to enter the required maximum input power for the equipment. This quantity usually appears on the equipment nameplate. You must enter a value with appropriate units of measure for the standard that you are using. The units of measure depend on the type of equipment. The software specifies the units of measure in the Data Dictionary Manager.

Rated voltage

Select the input voltage at which the equipment is designed to operate. This quantity ensures electrical compatibility between the electrical supply and the equipment. It usually appears on the equipment nameplate.

Number of phases

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

Supply

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

Frequency (Hz)

Select the operating frequency of the equipment. This property applies for an AC supply only.

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 the Load Data 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.

Phase arrangement

Select the required value to determine which of the available phases are in use for the current equipment, for example 3 PH + N (three phases plus neutral). This property applies for an AC supply only and the values on this list that are available for selection depend on the number of phases that you have selected.

Full load current (FLA)

The electrical current, in amperes, that the equipment draws from the supply when operating at maximum power. The full load current usually appears on the equipment nameplate. 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.

Resistive losses

Allows you to enter a value for the active power loss that is caused by the resistance of the windings (copper losses). The software uses this value when taking into account the converting equipment power losses when calculating batch load association and generating an All Feeder Load Summary report. The software takes into account these losses if you set your report preferences accordingly. (Select File > Preferences > Reports and then select Account for converting equipment power losses.)

Reactive losses

Allows to enter a value for the reactive power loss that is caused by the magnetic effects in the core (iron losses). The software uses this value when taking into account the converting equipment power losses during batch load association and generating an All Feeder Load Summary report. The software takes into account these losses if you set your report preferences accordingly. (Select File > Preferences > Load Summaries and Reports and then select Account for converting equipment power losses.)

Electrical power

Entering electrical power values allows you to include these values in the calculations of load summaries, batch load associations, and when generating all feeder load summary reports. When performing a drill-down calculation for a PDB that has a branch connected to a bus through a consumer converting equipment item, the software accounts for the total of this branch using the electrical power values of this converting equipment item. Note that the software will use these values only if the current converting equipment has been defined as a consumer. See Define Converting Equipment as Consumers.

Rated active load

Allows you to enter an appropriate rated active load value.

Rated reactive load

Allows you to enter an appropriate rated reactive load value.

Rated apparent load

Displays the rated apparent load value calculated by the software.

Consumed active load

Allows you to enter an appropriate consumed active load value.

Consumed reactive load

Allows you to enter an appropriate consumed reactive load value.

Consumed apparent load

Displays the consumed apparent load value calculated by the software.

Secondary output

This section provides information about the output from the equipment. When the converting equipment is a transformer, the software displays the item tags for the secondary windings, as well as appropriate information according to whether the transformer design has one or two sets of secondary windings. Note that this section is available for all types of converting equipment apart from current limiting reactors. The name of the secondary equipment appears after a slash in this label.

Rated power

Displays the maximum output power for the equipment.

  • For two-winding transformers, the rated power of the secondary winding is copied automatically from the primary rated power.

  • For three-winding transformers, the rated power of each secondary winding can be smaller or equal to the rated power of the primary winding. Both secondary windings can have the same rated power value as long as the rated power value of neither secondary winding exceeds the rated power value of the primary winding.

Nominal current

Enter the output current for the converting equipment, including appropriate units such as amperes. For a transformer, this is the current in the secondary windings.

Rated voltage

Select the output voltage at which the equipment is designed to operate. This quantity ensures electrical compatibility between the electrical supply and the equipment. It usually appears on the equipment nameplate.

Current limiting reactors

This section enables you to define the reduction of the short- circuit power of networks or installations to an acceptable value with regard to the short-circuit strength of the equipment or the breaking capacity of the circuit breaker.

Insulation level

Allows you to enter the rated voltage level for the insulation of the equipment.

Resistance

Allows you to enter the resistive value of the current limiting reactor.

Reactance

Allows you to enter the reactance values of the current limiting reactor.

Short circuit current [RMS]

Allows you to enter the level of fault current (Root Mean Square).

Short circuit current [Peak]

Allows you to enter the maximum level of the fault current.

Power factor

Allows you to enter an appropriate power factor for the current limiting reactor.

Basic impulse level

Allows you to define the maximum voltage level for the impulse test of the current limiting reactor.

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.
