2 Functions
The data can be retrieved via the serial interfaces by means of a personal computer
and evaluated with the operating software DIGSI
SIGRA 4. The latter graphically represents the data recorded during the system fault
and also calculates additional information from the measured values. A selection may
be made as to whether the measured quantities are represented as primary or sec-
ondary values. Binary signal traces (marks) of particular events, e.g. „fault detection",
„tripping" are also represented.
If the device has a serial system interface, the fault recording data can be passed on
to a central device via this interface. The data is evaluated by applicable programs in
the central device. The measured quantities are referred to their maximum values,
scaled to their rated values and prepared for graphic representation. Binary signal
traces (marks) of particular events, e.g. „fault detection", „tripping" are also represent-
ed.
Where transfer to a central device is possible, the request for data transfer can be ex-
ecuted automatically. It can be selected to take place after each fault detection by the
protection, or only after a trip.
