Technical manual
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.
