10 Transient Fault Recorders

– TFR

The transient fault recorder saves the current phases and

State

during 1 s with the resolution 2 000 Hz,

including the time that is specified by the parameter

Pretrigger

. See chapter 8.2. for more details on

State

.

Disturbance recorder data is found on subtab

Status/TFR data

. If there are more than one detector, one

file per detector is saved regardless of which one that triggers the recording. To download the interference
file, simply click on the button

Detector 1

,

Detector 2

or

Detector x

. Depending on the browser settings, you

can select the file name and destination for the download.

The

Type

column specifies what triggered the file to be saved. For example, the earth fault function may

have started. The following events trigger the transient fault recorder:

▪

START

overcurrent

▪

START

earth fault

▪

START

non-directional earth fault

▪

Manual trigger by pressing

Capture active live data

. See Figure 13.

The rightmost column contains a button,

Acknowledge

. The purpose of the function is that non-

acknowledged disturbances files should not be overwritten and valuable information lost. A disturbance file
can be acknowledged in several ways:

1.

Press the button for the respective interference in the

TFR data

subtab. Only this specific

disturbance is acknowledged.

2.

Press the physical button on the IPC device. All disturbances are acknowledged.

3.

By automatic acknowledgment after some time, a setting on the

Config/Detector/Common

subtab.

All disturbances are acknowledged.

4.

By sending a telegram,

single command

to the device, addressing

Acknowledge

, binary outputs. All

disturbances are acknowledged.

A maximum of nine disturbances are saved. Only a disturbance that is acknowledged can be discarded. The
oldest acknowledged disturbance will be next to be discarded. This means that after an acknowledgment,
IPC402x is always ready to register a new disturbance record.

The disturbance records are stored in non-volatile memory. It is possible to erase individual or all
disturbance records manually, i. e., after commissioning and/or testing.
