ADVANTAGES
• All of the advantages of a fully numeric
product in an economical “current only”
protection package.
• Compact design requires minimal panel
space for overcurrent and reclosing
applications.
• Adds Oscillography, Sequence of Events,
and Metering when single function current
relays are replaced with the BE1-700C.
• BESTlogic provides the user with
complete flexibility in configuring a
protection and control system. User
programmable variable and switch
names make these relays completely
self documenting.
• Programmable LCD display allows
the relay to replace local indication and
control functions, such as panel metering,
alarm annunciation, and control switches.
• Two independent communication ports
with protocol support allows integration
with distributed control systems.
• Available with or without reclosing.
• Optional BESTNet Ethernet package
provides metering and status web pages,
settings and configuration via Ethernet,
and email notification of user-defined
events.

BE1-700C
Digital Overcurrent
Protective Relay
The BE1-700C Overcurrent Protection
System provides three phase, ground,
and negative sequence overcurrent
protection and is intended for use in any
non-directional overcurrent protection
application. Its unique capabilities make
it ideally suited for applications with the
following requirements:
• Applications that require low burden to
extend the linear range of CTs.
• Applications that require the flexibility
provided by wide setting ranges, multiple
setting groups, and multiple coordination
curves in one unit.
BESTCOMS allows you to:
• Enter settings and BESTlogic logic
equations for the BE1-700
• Save settings to a file
• Save BESTlogic logic schemes
(without settings) to a “Logic Library” file
• Print settings
• Upload and download settings
via Serial port
• Upload and download settings via
Ethernet (with BESTNet option)
• View real-time metering and status when
connected to a relay
• View fault records and SER data when
connected to a relay
• View COMTRADE oscillographic records
(with included BESTwave program)

• Applications that require the economy
and space savings provided by a multi
function, multiphase unit. This one unit
can provide all of the protection, as well
as local and remote indication, metering,
and control functions required on a
typical circuit.
• Applications that require communication
capability.
• Applications that require a fundamental
digital signal processing (DSP) algorithm
to provide rejection of harmonics and
low transient overreach.
• Applications where bus protection is
provided by a high speed bus overcurrent
blocking scheme instead of a dedicated
bus differential circuit.
• Applications where the capabilities of
intelligent electronic devices (IEDs) are
used to decrease relay and breaker
maintenance costs.
• Applications using Ethernet communication,
programmable email notifications, and
live metering information via an embedded
web server (with BESTNet option).

ORDERING INFORMATION
BESTlogic SPECIFICATIONS
The BE1-700C is a multifunction, numeric
relay that provides a comprehensive mix of
protective, control and metering functions
in an integrated system. This system is
suitable for any nondirectional overcurrent
application including feeder applications,
generator/motor applications, cogeneration
applications, and transformer backup.
The unit has one set of three phase and
neutral current sensing inputs to provide
all common protective functions for typical
power distribution overcurrent protection
applications.
Two independent communications ports,
along with built-in support for ModbusTM or
Modbus TCP, provide easy access to
integrating the protection, control, metering,
and status monitoring functions into a
substation automation system. The
standard IRIG-B port provides time
synchronization from a master clock.
Real time metering provides amp and
unbalance loading telemetry for the
protected circuit. Contact sensing inputs
and alarm monitoring functions provide
real time status information. Remote
control is provided by virtual control and
selector switches with select-before-
operate control of programmable outputs.
BESTlogic
BESTlogic programmable logic provides
the user with high flexibility in configuring
a protection and control system.
Each of the protection and control functions
in the BE1-700C is implemented as an
independent function block that is equivalent
to its single function, discrete device
counterpart. Each independent function
block has all the inputs and outputs that
the discrete component counterpart
might have. Figures 5 and 5a show each
of the independent function blocks
available for use in the BE1-700C.
Programming BESTlogic is equivalent to
choosing the devices required by your
protection and control scheme and
drawing schematic diagrams to connect
the inputs and outputs to obtain the
desired operational logic.
The BE1-700C relay can store, as user
settings, one user programmable, custom
logic scheme. To save you time, several
preprogrammed logic schemes have also
been provided. Any of the preprogrammed
schemes may be copied into the logic
settings without making any additional
BESTlogic settings.
BESTlogic provides the protection engineer
with the flexibility to set up this powerful
multifunction system 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.

external connections, and Figure 4 shows

FUNCTIONAL DESCRIPTION
BESTNet ETHERNET OPTION
The BESTNet option connects your
BE1-700C relay to the wired world.
BESTNET features include:
• Embedded web server with metering,
status, and fault summary information*
• Email alerts of as many as seven
user-defined conditions**
• Full BESTCOMS support over Ethernet
• Full Basler ASCII protocol for terminal
mode communications (TELNET) or
custom programmed application access
• Support for DHCP or static IP
addressing. IP Discovery function
included in BESTCOMS.
* A web browser with a Java™ Runtime
environment installed is required to view
web pages.
** An external SMTP email server must be
available to use email alerts.
Modbus/TCP ETHERNET OPTION
Instead of the BESTNet option, the
BE1-700 can be ordered with the
Modbus/TCP option. With Modbus/TCP,
your BE1-700 relay offers a true
Modbus/TCP protocol connection via an
internal 10/100 BaseT port. No clumsy
external adaptors are required! Simply
plug in an Ethernet cable and your BE1-
700 is part of your Modbus/TCP network.
NOTE: Modbus/TCP and BESTNet are mutually
exclusive. The Ethernet port can be used for
BESTNet or Modbus/TCP, but not both.
