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 and settings information (refer
times definition). Figure
tested for a typical configuration. In a 60 Hz system, it is possible to record 80 disturbance
recordings where the average recording time for each disturbance recording file is 3.4 seconds
with 40 analog and 96 binary signals in each recording. The memory limit does not affect the rest
of the disturbance recordings report (Event list (EL), Event recordings (ER), Indications (IND) and
Trip value recordings (TVR)).

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).

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.
