SECTION 5
• METERING
INTRODUCTION
The BE1-700 Digital Protective Relay measures the voltage and current inputs, displays those values in
real time, records those values every ¼ second, and calculates other quantities from the measured
inputs.
METERING FUNCTIONS
BE1-700 metering functions include voltage, current, and frequency. Metered values are viewed through
any communication port using serial commands or at the front panel human-machine interface (HMI).
Metering functions are summarized in the following paragraphs and in Table 5-2. For assistance with
navigating through the HMI metering screens, refer to Section 10, Human-Machine Interface.
Auto Ranging
The BE1-700 automatically scales metered values. Table 5-1 illustrates the ranges for each value
metered. C under the Type column refers to the BE1-700C relay; V refers to the BE1-700V relay.

Whole Units Kilo Units Mega Units
C Current 0 A to 9,999 A 10 kA to 9,999 kA 10 MA
V Voltage 0 V to 999 V 0 kV to 999 kV 1 MV

BESTCOMS
™ Metering Screen
Metered values are viewed through the BESTCOMS
™ Metering screen (see Figure 5-1). To open the
Metering screen, select Metering from the Reports pull-down menu. To begin viewing metered values,
select the Start Polling button in the bottom right of the screen.
Alternately, metering can be performed through the use of the ASCII command interface or HMI using
Screens 3.1 through 3.11.
Refer to Table 5-2 for a list of ASCII commands and HMI Screens used for metering. C under the Type
column refers to the BE1-700C relay; V refers to the BE1-700V relay; A refers to both relays.
