Allows you to specify values for connections and tapping on the primary transformer winding.

Tag

Identifies the transformer. The tag is the name that appears beside the item in the Electrical Index. The tag matches the naming convention for the item.  Select the ellipsis button to open a dialog where you can modify the tag segments that are editable.

Connection

Allows you to select the type of connection for a 3-phase input.

Neutral grounding

Allows you to specify whether to use neutral grounding.  The following standard options are available:

Ungrounded

Does not require grounding.

Solid grounding

Grounding is achieved by means of a cable connected directly to ground.

Impedance

Grounding is achieved by means of a cable connected to ground via a resistor.

Grounding cable

Allows you to specify a grounding cable when the Neutral grounding value is Solid grounding or Impedance. Select the ellipsis button to open the Find dialog from which you can select a suitable grounding cable. Note that for a cable to be available for use as a grounding cable, its Neutral Earthing property must be set to True.

Grounding resistor

Allows you to specify a resistor when the Neutral grounding value is Impedance. You can use a grounding resistor with or without a grounding cable. Select the ellipsis button to open the Find dialog from which you can select a suitable resistor. You define resistors under Static Electrical Equipment in the Electrical Index. Note that on the Find dialog, the software retrieves all the existing resistors regardless of whether they have or have not been associated with transformers. Make sure that you select an appropriate resistor that has not been associated yet.

Tapping options

Tapping required

Allows you to enable the tapping options.

Tapping

Allows to select a tapping option. The options are for information only and do not affect the ability to enter data values for the other properties in this section.

Tapping percentage per step

Allows to type the percentage of the total winding length to be used for each step interval for tapping.

Number of steps

Allows to type the total number of tapping points required along the winding.

Total tapping percentage range

The calculated value of the product of the tapping percentage per step and the number of steps.

Neutral Earthing Metering Equipment

Component Type

Displays the Component Type.

Component Tag

Displays the Component Tag number.

Order

Shows the order of appearance of the metering equipment on your drawing, the lower the number the closer to the winding.

Add

Opens the Find dialog and lists available PT/CT whose Neutral Earthing flag is False.

Remove

Removes the selected component.
