shows the number of recordings versus the total recording time tested for a typical
configuration, that is, in a 60 Hz system it is possible to record 80 where the average
recording time is 3.4 seconds. The memory limit does not affect the rest of the
disturbance report (Event list (EL), Event recorder (ER), Indications (IND) and Trip
value recorder (TVR)).

might cause disturbance recordings to be deleted due to lack of disk space.
