Fault Records 3.2 Fault record settings 56 SIPROTEC, SIGRA, Manual E50417-H1176-C070-B1, Edition 06.2017 SIGRA135.tif Figure 3-2 An example of the representation of vector diagrams in table form Click the Measuring Signal box of Cursor 1 and select a signal from the list box, e.g. VL1; click the Measuring Signal box of Cursor 2 and select a signal from the list box, e.g. VL2. The cursor position on the time axis is displayed in the Time in ms box. The other boxes display the respective values of the signal at this instant. Meaning of the lines: C2 - C1 This line shows the difference (time and values) calculated by SIGRA. C2 + C1 This line shows the sum (values) calculated by SIGRA. C2 / C1 This line shows the quotient (values) calculated by SIGRA. C2 * C1 This line shows the product (values) calculated by SIGRA. 3.2.2 Assigning instants Cursor 1 / Cursor 2 The current cursor position on the time axis is shown in the tables of all views. In the Time Signals view, the cursors are also displayed by a vertical line across all diagrams, in the Circle Di- agrams view they are represented as a small crosshair or, if a measured signal has been assigned, as a large crosshair. The cursors are color-coded. The color assignment can be found in the cursor symbol, line or crosshair, the tables and in the dialogs. Only cursor 1 is used for measuring in the Harmonics view. Positioning the cursor To position a cursor at a defined instant, proceed as follows: Click the cursor symbol and keep the left mouse button pressed. Move the cursor along the time axis to the left or the right. You can follow the positioning along the time axis in Time in ms box of the table. Release the mouse button when you have reached the desired point; or enter the instant in Time in ms box of the table. SIGRA then sets the cursor automatically to this instant;

SIGRA then shifts the cursor automatically to this point. In the Circle Diagrams view, you can also position the cursor at a defined sampling instant as follows: Assign a signal to the cursor. The cursor is displayed as a large crosshair; spproach the intersection of the cursor lines with your mouse pointer. The mouse pointer changes to a hand symbol. Keep the left mouse button pressed and move the hand to the required sampling instant. 3.2.3 Determining cursor behavior Magnetic cursor lines With the Options > Magnetic Cursor Lines menu command you can synchronize the movement of a cursor along the time axis quickly and exactly with: status changes of binary signals and status signals (marking of significant instants) When a cursor approaches such an event, it is attracted “magnetically” and "snaps" to that point.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
