Monitoring
• Disturbance reports are not stored.
• LED information (yellow - start, red - trip) is not stored or changed.
Operation = On :
• Disturbance reports are stored, disturbance data can be read from the local HMI and from
a PC for example using PCM600.
• LED information (yellow - start, red - trip) is stored.
Every recording will get a number (0 to 999) which is used as identifier (local HMI, disturbance
handling tool and IEC 61850). An alternative recording identification is date, time and
sequence number. The sequence number is automatically increased by one for each new
recording and is reset to zero at midnight. The maximum number of recordings stored in the
IED is 100. The oldest recording will be overwritten when a new recording arrives (FIFO).
18.6.4.1 Recording times
The different recording times for Disturbance report are set (the pre-fault time, post-fault
time, and limit time). These recording times affect all sub-functions more or less but not the
Event list (EL) function.
Prefault recording time (
disturbance. The setting should be at least
of pre-fault values in the Trip value recorder (TVR) function.
Postfault recording time (
disappearance of the trig-signal (does not influence the Trip value recorder (TVR) function).
Recording time limit (
limits the recording time if some trigging condition (fault-time) is very long or permanently set
(does not influence the Trip value recorder (TVR) function).
Operation in test mode
If the IED is in test mode and
any recordings and no LED information is displayed.
If the IED is in test mode and
mode and the status is indicated in the saved recording.
Post Retrigger
Disturbance report function does not automatically respond to any new trig condition during a
recording, after all signals set as trigger signals have been reset. However, 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 (
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 (
