Measurement Functions Setup
The BE1-951 requires information about the power system and its current and voltage transformers to
provide metering, fault reporting, fault location, and protective relaying. This information is entered using
BESTCOMS. Alternately, it may be entered at the HMI (see Section 10, Human-Machine Interface) or
through the communication port using the following ASCII commands: SG-CT, SG-VTP, SG-VTX, SG-
FREQ, SG-NOM, and SG-PHROT. The SG-LINE command for Power Line Parameters is found Section
6, Reporting and Alarm Functions, Fault Reporting, Distance to Fault.
Power System Settings
To enter power system settings, select General Operation from the S
creens pull-down menu. Then select
