ABB RET670 - Setting Guidelines

The event recorder information is available for each of the recorded disturbances in the
IED and the user may use the local HMI to get the information. The information is
included in the disturbance recorder file, which may be uploaded to PCM600 and
further analyzed using the Disturbance Handling tool.
The event recording information is an integrated part of the disturbance record
(Comtrade file).
3.15.9.2 Setting guidelines
The setting parameters for the Event Recorder (ER) function are a part of the
Disturbance Report settings.
It is possible to event handle up to 96 binary signals, either internal signals or signals
from binary input channels. These signals are identical to the binary signals recorded
by the disturbance report.
For the ER function there is no dedicated setting.
3.15.10 Trip value recorder
3.15.10.1 Application
Fast, complete and reliable information about disturbances such as fault currents and
voltage faults in the power system is vital. This information is used for different
purposes in the short perspective (for example, fault location, disturbance analysis,
corrective actions) and the long term (for example, disturbance analysis, statistics and
maintenance, that is Functional Analysis).
The trip value recorder (TVR), always included in the IED, calculates the values of all
selected external analog input signals (channel 1-30) connected to the Disturbance
Report function. The estimation is performed immediately after finalizing each
recording and available in the disturbance report. The result is magnitude and phase
angle before and during the fault for each analog input signal.
The information is used as input to the fault location function (FL), if included in the
IED and in operation.
The trip value recorder (TVR) information is available for each of the recorded
disturbances in the IED and the user may use the local HMI to get the information. The
information is included in the disturbance recorder file, which can be uploaded to
PCM600 and further analyzed using the Disturbance Handling tool.
