Section 13
Monitoring
The event recorder information is available for the disturbances locally in the IED.
The event recording information is an integrated part of the disturbance record (Comtrade file).
13.8.2 Function block
The Event recorder has no function block of it's own.
13.8.3 Signals
13.8.3.1 Input signals
The Event recorder function logs the same binary input signals as the Disturbance report function.
13.8.4 Operation principle
When one of the trig conditions for the disturbance report is activated, the event recorder logs
every status change in the 96 selected binary signals. The events can be generated by both internal
logical signals and binary input channels. The internal signals are time-tagged in the main
processor module, while the binary input channels are time-tagged directly in each I/O module.
The events are collected during the total recording time (pre-, post-fault and limit time), and are
stored in the disturbance report flash memory at the end of each recording.
In case of overlapping recordings, due to
during post-fault time, events will be saved in both recording files.
The name of the binary input signal that appears in the event recording is the user-defined name
assigned when configuring the IED. The same name is used in the disturbance recorder function ,
indications and event recorder function.
The event record is stored as a part of the disturbance report information and managed via the
local HMI or PCM600.
