Display Object Options

 

The Display Object Options page is found on the Oneline Display Options dialog. This page contains options for formatting various display objects, displaying circuit breakers on loads, generators, and switched shunts, and formatting circuit breakers for transmission branches.

 

General Options (All) Tab

 

Percent of Injection Group/Owner object height used by name

This option allows the user to specify the height of the name with respect to the rectangle of the injection group graphical objects.

Display Circuit Breakers in Generators, Loads and Switched Shunts

Uncheck this box to hide circuit breakers from appearing in generators, loads, and switched shunts. If this option is checked, the user can use Display breakers on… to select individually what elements can display circuit breakers.

These options dictate only if circuit breakers will be shown on elements that are closed, i.e. Status = Closed for the individual element. Circuit breakers will always be shown for devices that are open, i.e. Status = Open for the individual element. This is useful in identifying possible data errors especially for cases where breakers are explicitly modeled. In these cases, the explicitly modeled breakers are used to open and close generators, loads, and switched shunts rather than changing the Status of the device. An open circuit breaker symbol at the individual elements would then indicate that the Status of the device needs to be set to Closed.

Circuit Breaker Size ScalarAdded in version 23 patch on April 19, 2024

Change this scalar to make the circuit breakers on loads, generators, and shunts larger or smaller. A value of 1.000 is the traditional size.

Transformer Symbol

This option allows the selection of Coils or Circles to represent a transformer. This option allows a different specification of how transformers should be displayed for each individual oneline diagram. There is also an option that is applied by default for all onelines. Use the Default selection to use the setting found with the Simulator Options: Oneline options.

Display Rotors in Generators

Uncheck this box to hide the rotors of the generators.

The shape of the rotor can be changed by using the Rotor Shape option found with the generator display options on the generator dialog in Edit mode or the Shape option found on the Display/Size tab of the Format Multiple Objects dialog.

Change in Gen Rotor Angle per Refresh (degrees)

This value specifies the change in the rotor angle every time the animated flows refresh. This means that the greater the angle value, the faster the rotor will seem to rotate when the oneline is animated. Entering a negative number will cause the rotor to spin counter-clockwise.

Show Field Inside Generator

Fields can be shown inside generator objects. Select a field from the drop-down box or use the Find button to search through the list of fields available for a generator. Set the field to No Field to not display any field inside generator objects. Set the Digits and Decimals for floating point fields. Adjust the Relative Font Size to change the size of the font relative to the generator object size. To ensure that the field fits entirely inside each generator object, check the option to Dynamically decrease the font size so that the field fits inside the generator.

Multi-Section Line Display Objects

Intermediate Bus Rotation Angle

Normally, the intermediate buses are perpendicular to the line. The value entered here can rotate the intermediate bus with respect to the original position. Therefore, a value of 0 degrees, will keep the intermediate buses perpendicular to the line, while a value of 90 degrees will set the intermediate buses aligned to the line.

Intermediate Bus Relative Size

This option is actually a multiplier for the size of the intermediate buses specified for each multi-section display object.

Bus Field Voltage Option

This option allows the user to specify in which units the bus fields with Bus Voltage as type of field will be displayed. This setting is only valid when the type of field selected is Bus Voltage in the Bus Field Information dialog. Choosing a voltage field in the Select Field will return the voltage value in the specific units of the field.

 

Circuit Breakers Tab

 

Circuit Breaker Display Objects > Normally Closed 

This section is used to specify the colors for all the circuit breakers normally closed in the oneline diagram. The colors that can be modified are the border and fill colors for presently closed and open circuit breakers. In order to change a color, click on the color box or on the Change button. Check Use Fill to use the specified fill color.

Circuit Breaker Display Objects > Normally Open

This section is used to specify the colors for all the circuit breakers normally open in the oneline diagram. The colors that can be modified are the border and fill colors for presently closed and open circuit breakers. In order to change a color, click on the color box or on the Change button. Check Use Fill to use the specified fill color.

Shape

Specify the shape of circuit breakers on transmission lines and transformers. The breakers shown on loads, generators, and switched shunts will always be the default rectangle shape.
