15. DATA RECORDERS
15.1. DAR - Digital and Analog Recorder
All
u REG
units are equipped with an additional current / voltage / digital data recorder
located in the IF-x module (also referred to as the disturbance recorder ), which is associated
with selected events affecting protective decisions.
The recorder memory is divided into buffers.
Each buffer always records 10 electrical values:
→ Configuration with VT-0 → Configuration with VT-2/VT-1 → Configuration with
VT-3/VT-4
1 set of voltages and currents 2 sets of voltages, 1 set of cI0 2 sets of voltages, 2 sets of currents

and 96 digital states (outputs of functors → see Log CZIP APPLICATION ).
Data are recorded in buffers in numerals (the so-called samples) with at a standard
frequency of 1600 Hz – 32 samples per period for each data set, according to the monitored
values directly at device terminals.
Available for each version of the IF-x module, the recorder memory can be configured to
support up to 10, 11 to 19 or even several tens buffers of different capacity.
In a standard solution, the following configurations of recorder buffers are available at 1600
Hz – [IF-0 4MB] / [IF-4 8/16MB] :

2*20.48 s (2 buffers, 20.48 s each),

4*10.24 s,

8*5.12 s,

16*2.56 s,

32*1.28 s,

2*40.96 s,

4*20.48 s,

8*10.24 s,

16*5.12 s,

32*2.56 s.
Additionally, the range of buffer configuration in the IF-4 [8/16 MB] module is extended over
the following settings :

2*81.92 s,

4*40.96 s,

8*20.48 s,
