Technical Manual
under certain circumstances the fault condition may reoccur during the post-fault
recording, for instance by automatic reclosing to a still faulty power line.
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.
