Oscillographic Fault Records

2.1.4
The 7SD80 multifunctional protection with control is equipped with a fault record memory. The instantaneous
values of the measured values
i , i , i , i , i und v
A B C E EE
(voltages in accordance with connection) are sampled at intervals of 1.0 ms (for 50 Hz) and stored in a
revolving buffer (20 samples per cycle). In the event of a fault, the data is stored for a set period of time, but
not for more than 5 seconds. Up to 8 fault events can be recorded in this buffer. The fault record memory is
automatically updated with every new fault so that there is no acknowledgment for previously recorded faults
required. In addition to protection pickup, the recording of the fault event data can also be started via a binary
input or via the serial interface.
