The memory limit does not affect the rest of the disturbance report (Event list, 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.
14.4.6.1 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

14.4.6.4 Event list
The event list may contain a list of totally 1000 time-tagged events. The list
