FAULT RECORD EVENTS

An event record is created for every fault the IED detects. This is also known as a fault record.
The event type description shown in the Event Text cell for this type of event is always Fault Recorded.
The IED contains a separate register containing the latest fault records. This provides a convenient way of viewing
the latest fault records and saves searching through the event log. You access these fault records using the Select
Fault setting, where fault number 0 is the latest fault.
A fault record is triggered by the Fault REC TRIG signal DDB, which is assigned in the PSL. The fault recorder
records the values of all parameters associated with the fault for the duration of the fault. These parameters are
stored in separate Courier cells, which become visible depending on the type of fault.
The fault recorder stops recording only when:
The Start signal is reset AND the undercurrent is ON OR the Trip signal is reset, as shown below:
Start signal resets
Undercurrent is ON
Trip signal resets

Figure 120: Fault recorder stop conditions

The event is logged as soon as the fault recorder stops. The time stamp assigned to the fault corresponds to the
start of the fault. The timestamp assigned to the fault record event corresponds to the time when the fault
recorder stops.
Note:
We recommend that you do not set the triggering contact to latching. This is because if you use a latching contact, the fault
record would not be generated until the contact has been fully reset.
