BE1 Numerical Systems provide state of the art protection, metering, and control functions in economical, yet powerful,
multifunction devices. Numerical technology enables these intelligent electronic devices to provide all functions required for a
zone of protection along with wide ranges, multiple setting groups, multiple coordination curves, and low burden. In addition to
this, most BE1 Numerical Systems provide options of both rack mount and retrofit friendly packages to facilitate modernizing
protection and control systems in existing facilities.
BESTlogic programmable logic provides the user with complete flexibility in
configuring a protection and control system. Each of the functions in a BE1 Numerical
Systems relay is implemented as an independent function block that is equivalent to its
single function, discrete device counterpart. This programmable logic system was
designed with users in mind to be immediately familiar to protection engineers and
technicians. BESTlogic allows the flexibility to set up these powerful multifunction
systems with the same freedom that was once enjoyed with single function, discrete
devices. It is no longer necessary to compromise your standard protection and
operating practices to deal with the limitations in programmability of previous
multifunction devices.
To ease the difficulty of setting up these complex, sophisticated devices,
BESTCOMS software is provided free of charge. This point and click
tool makes the process of creating settings files easy and intuitive and
reduces the learning curve. In addition, the ASCII command interface
allows access to the complete functionality of the device without the
requirement for proprietary software on your computer.
Extensive reporting and alarm functions are provided to help you monitor
equipment, restore systems, improve service, and reduce maintenance.
Detailed sequence of events reporting (SER), fault summary reports, and
oscillography recording allow detailed analysis of operations to determine
the cause of relay operations. Free BESTwave COMTRADE viewer
software allows you to open up to four oscillography files simultaneously
to aid in event analysis.
The three independent communications ports along with built in
support for Modbus
™ and DNP 3.0 provide easy access to
integrating the protection, control, metering, status reporting, and
monitoring functions into a substation automation system. The
standard IRIG-B port provides time synchronization from a
master clock. Remote control is provided by virtual control and
selector switches with select before operate logic through
programmable outputs.
