Fault records
The fault record needs to be separately configured for the desired registration actions.
For example, registrations can be defined to be made only at operate (trip) situation,
or also at any start on/off situation. The fault record function component contains all
registration object values that could have potentially been used by the relay type in
question. It depends on the relay variant type and the relay configuration if a certain
registration is made. Objects that are not registered remain constantly at value 0.
The fault record registers several values at the same time. All values belonging to the
same fault get the same ASDU 4 event time stamp. This makes it easy to collect
registrations belonging to the same fault situation.
ASDU 4 events can easily fill up the Class 1 event buffer. The fault record can for
example be configured to register only after an operate (trip) event. In such case, the
registration value events are generated and transmitted following the last “Breaker
open” event, when the relay is idle.
3.3.6 Energy counters
Counters are not defined by the IEC 60870-5-103 standard in general. A private data
unit ASDU 205 is used to define counters. All IEC 60870-5-103 masters does not
support this non-standard ASDU type.
