In order to capture the new disturbance it is possible to allow retriggering (
PostRetrig
=
Enabled
) during the post-fault time. In this case a new, complete recording will start and,
during a period, run in parallel with the initial recording.
When the retrig parameter is disabled (
PostRetrig
=
Disabled
), a new recording will not
start until the post-fault (
PostFaultrecT
or
TimeLimit
) period is terminated. If a new trig
occurs during the post-fault period and lasts longer than the proceeding recording a new
complete recording will be started.
Disturbance report function can handle maximum 3 simultaneous disturbance recordings.
