③ In accordance with the current phase order setting, the vector diagram, the RMS
values and the phase difference are displayed.
･ Their values for 1 cycle before the cursor position are calculated.
･ The reference phase is marked with [*].
･ You can update the vector diagram and the values by moving the cursor.
･ You can display 2 or more vector diagrams at a time. Activate other cursor and click [Analysis], and then
click [Vector Diagram].
Note: In the case of phase-to-phase voltage input in the GRD130 relay, phase-to-phase voltages are
displayed in the phase voltage columns. (Vab, Vbc and Vca are displayed at the Va, Vb and Vc
positions.)
④ To print the vector diagram, click [File], and then click [Print].
･ When you print the vector diagram, make the vector diagram screen fit within the main waveform analysis
screen.
⑤ To close the vector diagram display, click [File], and then click [Close].
