13.1.4 Effect of events on load profiles
The following section describes the behavior of the profile and the setting of status bits
considering different events.
• Season Change
The activation or deactivation of the daylight saving time does not create any additional
entries in the buffer. The timestamp together with the DST bit contains enough
information to clearly identify when the season change occurred and if the buffer data
was captured when daylight saving time was active or not.
• Power Down
The following section describes the behavior of the profile and the setting of the status
bits considering different power down events. A “Power Down” event starts with the
complete loss of power in all connected phases and ends with the restoration of the
power in at least one of the connected phases.
o Power Down within one capture period
The Power Down event affects only one specific capture period. The affected
capture period will be marked with Power Down (PDN) bit in the profile status
at the end of the capturing period.
Example: a power down event (from 15:17 to 15:21) within the capture period
of 15:15 to 15:30. The entry at 15:30, marked with the PDN flag. Since a
power down doesn't affect the validity of billing data, the DNV flag is not set.

o Power Down across several capture periods
Table 18 show a power down event (from 01:17 to 04:21) affecting all capture
periods between 01:15 and 04:15. For the capturing periods which completely
fall into the power down event no entry is registered in the load profile buffer.
