The Add | Shape command in the DS Relays Window lets you add a graphical shape in the plot. Currently the shapes available in the DS Relays Window are “polyline” – a series of segments connecting adjacent points, “arc”, “mho” and “quad”. The shape can be saved as part of a curve collection in a PCC file.
To execute this command you must first select the shape location with the left mouse button.
TO ADD A NEW SHAPE:
1. Select the shape location.
Click the left mouse button once on the desired location of the new shape.
A red crosshair will appear at that location.
2. Select the Add | Shape command.
A dialog box will appear.
Select either Polyline, Arc, Mho or Quad from the drop-down combo box. Press OK.
The Shape Properties dialog box will appear.
3. Enter the shape properties.
POLYLINE
Enter the total number of points in the first entry of the data grid, labeled “Segment count”.
Enter into the data grid the x and y coordinates of the points.
X is in Amperes. Y is in seconds.
At the top of the dialog box, specify the line thickness, line color, and line style.
Press OK.
The polyline shape will appear on the plot.
ARC
Enter into the data grid the x and y coordinates of the center of the arc.
The coordinates are in primary ohms.
Enter the radius in primary ohms.
Enter the starting angle and sweep angle, both in degrees.
Specify whether the shape is closed.
If you select ‘Yes’, a line segment will be drawn between the beginning and end points of the arc.
At the top of the dialog box, specify the line thickness, line color, and line style.
Press OK.
The arc shape will appear on the plot.
MHO
Enter the diameter in primary ohms.
Enter the maximum torque angle in degrees.
Specify whether the shape is in the forward or reverse direction.
Specify the offset magnitude (in primary ohms) and angle (in degrees).
QUAD
Enter the top reactance line length (in primary ohms) and angle (in degrees).
Enter the bottom reactance line length (in primary ohms) and angle (in degrees).
Enter the right resistance blinder length (in primary ohms) and angle (in degrees).
Enter the left resistance blinder length (in primary ohms) and angle (in degrees).
