To select a transformer, select the desired options from the corresponding parameter lists.

The Calculated output voltage parameter refers to the voltage considering losses across all elements in the system. It is calculated based on other input parameters in the group.

The Output voltage value corresponds to the selected tap voltage. It is selected from the list and must be as close as possible but slightly greater than the Calculated output voltage value.

The Transformation ratio parameter reflects the relationship between the input and output voltages of the transformer. The value is calculated automatically.

In the left part of the pane, a simplified visualization of the selected transformer configuration is displayed. Labels with values of the key parameters provide the ability to assess efficiency of the equipment.

Controller

The pane provides controls for the controller selection and configuration.

To select a controller, select the desired options from the corresponding parameter lists.

The control unit must be capable of handling both operating and starting voltage and current.

In the left part of the pane, a simplified visualization of the selected controller configuration is displayed. Labels with values of the key parameters provide the ability to assess efficiency of the equipment.

Work Parameters

The pane provides a table with values of the following operating parameters:

• Surface voltage : Based on this value, you can select the required transformer tap.

• Total power consumption : Based on this value, you can select a transformer with an appropriate nominal power.
