Explanation
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
BE1-11
m
analog metering functions include voltage, frequency, current, power, differential, and energy.
Metered values are viewed through the Metering Explorer in BESTCOMS
Plus
, 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 BE1-11
m
automatically scales metered values. Table 30-2 illustrates the ranges for each value
metered.

Voltage - Primary and Secondary
The BE1-11
m
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
rd
harmonic auxiliary voltage (Vx 3
rd
Harmonic). The Phase VT
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 BESTCOMS
Plus
(Figure 30-2) and on the
Metering > Analog Metering > Voltage screen of the front-panel display. A phasor diagram is also
provided in BESTCOMS
Plus
