As an option, SIPROTEC

quence of Event Report (SER) for the elements in the device. Furthermore, the ele-

ments that are shown in the SER can be selected by the user.

The waveform and SER data are retrieved from the device memory by DIGSI

are saved as waveform capture in standard COMTRADE format.

4 program is used to convert the oscillographic data into graphical rep-

resentations that can be used to analyze the fault or the event captured by the device.

4 calculates additional values from the waveform data, e.g. impedances and

rms values, and displays the captured and calculated values in:

Analogue Curves with timebase (Time Signals),

Vector Diagrams,

Circle Diagrams, and

Harmonic graphs.
