Up to 100 disturbance reports can be stored. If a new disturbance is to be recorded when
the memory is full, the oldest disturbance report is overwritten by the new one. The total
recording capacity for the disturbance recorder is depending of sampling frequency,
number of analog and binary channels and recording time. In a 60 Hz system it is possible
to record 80 where the maximum recording time is 3.4 seconds. The memory limit does
not affect the rest of the disturbance report (Sequential of events, Event recorder,
Indications and Trip value recorder).
The maximum number of recordings depend on each recordings total
recording time. Long recording time will reduce the number of recordings
to less than 100.
The IED flash disk should NOT be used to store any user files. This might
cause disturbance recordings to be deleted due to lack of disk space.

Disturbance information

Date and time of the disturbance, the indications, events, fault location and the trip values
are available on the local HMI. To acquire a complete disturbance report the user must use
a PC and - either the PCM600 Disturbance handling tool - or a FTP or MMS (over 61850)
client. The PC can be connected to the IED front, rear or remotely via the station bus
(Ethernet ports).
Indications
Indications is a list of signals that were activated during the total recording time of the
disturbance (not time-tagged), see Indication section for detailed information.
Event recorder
The event recorder may contain a list of up to 150 time-tagged events, which have
occurred during the disturbance. The information is available via the local HMI or
PCM600, see Event recorder section for detailed information.
Sequential of events
The sequetial of events may contain a list of totally 1000 time-tagged events. The list
information is continuously updated when selected binary signals change state. The oldest
data is overwritten. The logged signals may be presented via local HMI or PCM600, see
Sequential of events section for detailed information.
