3.6.2.2 Automatic extraction procedure
There are two methods that can be used for automatically extracting disturbances. Option 1
is simpler and is better at extracting single disturbance records, i.e. when the disturbance
recorder is polled regularly. Option 2, however, is more complex to implement but is more
efficient at extracting large quantities of disturbance records. This may be useful when the
disturbance recorder is polled only occasionally and hence may have many stored records.
3.6.2.3 Automatic extraction procedure – option 1
The procedure for the first method is shown in the following figure. This also shows the
acceptance of the disturbance record once the extraction is complete.
