Overcurrent Screen. Pull down the Screens menu and select Overcurrent. If you wanted the specific
setting change that you were about to make to affect the Group 1 settings, select Group 1.
General Operation
Pull-down the Screens menu and select General Operation or click on the General Operation
icon that is shown at the right margin of this paragraph. This screen has five folder tabs (like
paper file folder tabs). The first tab is labeled General Information. When the screen is first
displayed, the General Information is in the foreground (the default) and the other tabs are in
the background. You may select any of these tabs and bring that tab and information into the foreground.
If you are at another BESTCOMS screen such as Overcurrent and want to return to this screen, you may
use the Screens pull-down menu or click on the General Operation icon that is shown at the right margin
of this paragraph.
General Information
This tab (Figure 14-4) allows you to fill in the style number of the relay that is available from the label on
the relay front panel. You can also enter the serial number and software application program information.
Additionally, you may enter the name of the substation and the feeders so that relay reports have some
form of installation-specific identification.

Power System
This tab (see Figure 14-5) allows you to enter the frequency, phase rotation, nominal CT secondary
voltage and current, and power line parameters. If the phase rotation entry is not correct, it will cause
problems in several areas including metering values and targets. Power line parameters are necessary
for line protection. In other words, you must make entries in these fields in order for the BE1-851
protection elements to function. These symmetrical component sequence quantities are entered to
provide immediate reference information for settings of the protection elements in the BE1-851 relay.
