For the program for viewing oscillogram in COMTRADE format, a function for calculating the frequency for analog signal from the oscillogram has been added.
For the program for viewing oscillograms in the COMTRADE format a functional for calculating the symmetric components for signals is added.
For the program for oscillogram viewing in COMTRADE format, the functionality of constructing the frequency spectrum for an arbitrary analog signal from the waveform is added.
For the Oscillogram Viewer in the COMTRADE format the functionality of constructing a vector diagram for analog channels has been added.
When buiding vector diagrams for three-phase circuits, the choice of a base vector is now available. When choosing a vector as the base one, its angle is taken equal to 0°, and the angles of the remaining vectors are counted relative to it.
