Oscillographic Fault Records
The Multifunctional Protection with Control 7SK80 is equipped with a fault record memory. The instantaneous

(voltages depending on connection) are sampled at intervals of 1.0 ms (at 50 Hz) and stored in a revolving
buffer (20 samples per cycle). In the event of a fault, the data are recorded for a set period of time, but not for
more than 5 seconds. A minimum of 8 faults can be recorded in this buffer. The fault record memory is auto-
matically updated with every new fault, so no acknowledgment for previously recorded faults is required. In ad-
dition to protection pickup, the recording of the fault data can also be started via a binary input or via the serial
interface.
2.1.4.1 Description
The data of a fault event can be read out via the device interface and evaluated with the help of the SIGRA 4
graphic analysis software. SIGRA 4 graphically represents the data recorded during the fault event and also
calculates additional information from the measured values. Currents and voltages can be presented either as
primary or as secondary values. Signals are additionally recorded as binary tracks (marks), e.g. "pickup", "trip".
If port B of the device has been configured correspondingly, the fault record data can be imported by a central
controller via this interface and evaluated. Currents and voltages are prepared for a graphic representation.
Signals are additionally recorded as binary tracks (marks), e.g. "pickup", "trip".
The retrieval of the fault data by the central controller takes place automatically either after each protection
pickup or after a tipping.
If device parameter 651 ParEN100(LC)blk is set to ON, you can also read out fault records via port A (see
Section 2.1.2.2).
