Breaker Control Switch (101)
Tripping and closing of a selected breaker can be controlled by the virtual breaker control switch. The
virtual breaker control switch is accessed locally at the front panel or remotely through the communication
ports.
Virtual Control Switches (43)
Five virtual control switches are accessed locally at the front panel or remotely through the
communication ports. Virtual switches can be used to trip and close additional switches or breakers, or
enable and disable certain functions.
Logic Timers (62)
Eight logic timers with six modes of operation emulate virtually any type of timer.
Lockout Functions (86)
Two lockout elements are provided.
BESTlogic
™Plus Programmable Logic
Each BE1-11g protection and control function is implemented in an independent function element. Every
function block is equivalent to its single function, discrete device counterpart so it is immediately familiar
to the protection engineer. Each independent function block has all of the inputs and outputs that the
discrete component counterpart may have. Programming with BESTlogicPlus is equivalent to choosing
the devices required by your protection and control scheme and then drawing schematic diagrams to
connect the inputs and outputs to obtain the desired operating logic.
Refer to the BESTlogicPlus chapter for more information on logic schemes. Custom logic settings allow
you to tailor the BE1-11g functionality to match the needs of your operation's practices and power system
requirements.
Metering Functions
Metering is provided for the following parameters:
•
Primary and secondary voltages (P-P, P-N, V1, V2, 3V0, Vx, Vx 3 rd harmonic)
•
Frequency (phase and auxiliary)
•
Primary and secondary currents (phase, ground, I1, I2, 3I0)
•
Power (real, reactive, apparent)
•
Power factor
•
Phase differential (Iop, Ir, 2 nd Harmonic, 5 th Harmonic)
•
Neutral differential (Iop)
•
Energy (total watthours and total varhours)
For details on metering functions, refer to the Metering chapter.
Model and Style Number Description
BE1-11g electrical characteristics and operational features are defined by a combination of letters and
numbers that make up the style number. The style number describes the options included in a specific
device and appears on labels located on the front panel and inside the case. Upon receipt of a BE1-11g,
be sure to check the style number against the requisition and the packing list to ensure that they agree.
The model number and style number are shown in Figure 1.
