All channels are recorded (IA, IA Circuit 2, IB, IB Circuit 2, IC, IC Circuit 2, IG, IG Circuit 2, VA, VB, VC,
VX, FP, FX, Analog Inputs, and RTDs) as they happen in real time.

A settings snapshot is taken and recorded with each event. This snapshot will be stored in a file that can
later be uploaded to the device to return it to the settings that were active at the time of the recording.

BE1-11g protection systems have three identification fields: Device ID, Station ID, and User ID. These
fields are used in the header information lines of the oscillographic records. Refer to the

BESTCOMSPlus

Software

chapter for information on BE1-11g identification settings.

Oscillographic Records Settings

The oscillographic records settings are programmed through BESTCOMSPlus. Use the Settings Explorer
to open the Metering Configuration, Fault Records screen as shown in Figure 140. Enter the values for
Sample Resolution, Number of Records to Store, and Prefault Cycles.

Figure 140. Fault Records Screen

Table 76 summarizes the oscillographic records settings.

Retrieving Oscillographic Records

Oscillographic records can be downloaded through the Reports, Fault Reports screen in BESTCOMSPlus
(Figure 139). See Fault Reports earlier in this chapter. Oscillographic records can also be downloaded
through the web page interface. For more information, refer to the

BESTnetPlus

chapter.

Distance to Fault

The BE1-11g calculates distance to fault each time a fault record is triggered. Distance to fault is
calculated and displayed based on the power line parameters entered using BESTCOMSPlus or the front-
panel interface. Table 77 provides the power line operating settings.
