The fault record data are retrieved from the device memory by DIGSI

stored as oscillographic records in standard COMTRADE format.

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

resentations that can be used to analyse 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),

phasor diagrams,

locus diagrams, and

harmonic graphs.
