A Holding the left mouse button down on a metering tab and dragging it to one of the four
arrow boxes will place it inside the selected window on the location selected. To place the
metering tab as a tab inside the selected window, drop it on the tabs button in the center
of the arrow buttons.
B This blue transparent square represents the screen being moved.
C Holding the left mouse button down on a metering tab and dragging it to the right, down,
left, or up arrow box will place it across the side/bottom/top of the screen. Click on the
(thumbtack) to dock it on the side bar. To display a screen that is docked, simply use the
mouse to hover the pointer over the tab on the side bar.

Analog Metering Functions

BE1-11g analog metering functions include voltage, frequency, current, power, synchronization, and
energy. Metered values are viewed through the Metering Explorer in BESTCOMSPlus, the front-panel
display, or the web page interface on Ethernet equipped protection systems. Refer to the BESTnet™Plus
chapter for more information. Metering functions are summarized in the following paragraphs. For
information on power, VA, and var calculations, refer to the Configuration chapter.
Auto Ranging
The BE1-11g automatically scales metered values. Table 77 illustrates the ranges for each value
metered.

Frequency 10 to 125 Hz
Voltage - Primary and Secondary
The BE1-11g meters primary and secondary phase-to-neutral voltages (VA, VB, VC), phase-to-phase
voltages (VAB, VBC, VCA), positive-sequence voltage (V1), negative-sequence voltage (V2), neutral-shift
voltage (3V0), auxiliary voltage (Vx), and 3
connection determines what is measured. The auxiliary voltage input is user selectable. Refer to the
Configuration chapter for more information on configuring Phase VT and AUX VT.
Primary and secondary voltage metering data is found in BESTCOMSPlus (Figure 129) and on the
Metering > Analog Metering > Voltage screen of the front-panel display. A phasor diagram is also
provided in BESTCOMSPlus.
