Another nowadays requested Push event is the First Breath.
This message is sent to the head end system (HES) as soon as the meter is powered up.
How useful is this information?
Imagine a power-fail at a distribution transformer with 1000 energy meters. Here it would be sufficient to monitor only the CT-meter behind the transformer. If this meter is up, you can assume that the whole area is energized.
The message from all individual meters is meaningless and causes only traffic.
The customer will not call you, because the power-fail has already been restored.
If you want to document your workers KPI (Key Performance Indicator) regarding the restore of power supply, you can do this more efficient by reading the meter log files. There you have the time of power fail and the time of power restore.
If you have the Last Gasp push event enabled you will get 1000 events.
For the First Breath you get another 1000 events.
This is only for one distribution transformer. You are monitoring hundred thousands of meters.
So use a Push alarm wisely.
Recently I had a discussion where a Last Breath function was requested. Fine, in DLMS terminology this would be Last Gasp :)
The meter has no voltage supply for a certain period. CLOU default is 30 seconds.
Are you already using the First Breath function?
What is your experience?
