Metering BE1-11m
Reactive Power
Reactive power is metered over a range of −4,500 kilovars to +4,500 kilovars on five-ampere nominal
systems. One-ampere systems meter reactive power over a range of −900 kilovars to +900 kilovars.
Phases A, B, C, and total phase are included.
Apparent Power
Metered apparent power is displayed over a range of –4,500 kilovoltamperes to +4,500 kilovoltamperes
on five-ampere nominal systems. One-ampere nominal systems meter reactive power over a range of
–900 kilovoltamperes to +900 kilovoltamperes. Phases A, B, C, and total phase are included.
Power Factor
Power factor is metered over a range of maximum lagging (−0.00) to unity (1.00) to maximum leading
(+0.00) for phases A, B, and C, and for total phase.

Frequency
Frequency is metered over a range of 10 to 125 hertz. If the measured frequency is outside this range,
the display will show “---“.
Frequency is sensed from Va to N on the back of the BE1-11m . Refer to the Typical Connections chapter
for three-wire and four-wire connection diagrams. The frequency of the auxiliary voltage input (VX) is also
measured.
Frequency metering data is found in BESTCOMSPlus (Figure 30-5) and on the Metering > Analog
Metering > Frequency screen of the front-panel display.
