BE1-11
m
Introduction
BE1-11
m
records and reports oscillography data in industry-standard IEEE, COMTRADE format to allow
using any fault analysis software. Basler Electric provides a Windows
®
based program called
BESTwave
™
that can read and plot binary or ASCII format files that are in the COMTRADE format. A
copy of BESTwave is included on the BE1-11 product CD.
Sequence of Events Recorder
A Sequence of Events Recorder (SER) records and time stamps all BE1-11
m
inputs and outputs as well
as all alarm conditions monitored by the BE1-11
m
. Time stamp resolution is to the nearest half-cycle. I/O
and Alarm reports can be extracted from the records as well as reports of events recorded during the time
span associated with a specific fault report.
Protection and Control
The BE1-11
m
includes protection elements that monitor voltage, current, power, phase angle, frequency,
temperature, and more to provide protection against faults and abnormal operating conditions. Control
elements make the BE1-11
m
capable of controlling complex distribution configurations. The following
paragraphs describe each protection and control function.
Undervoltage (27P) and Overvoltage (59P) Protection
Four phase undervoltage and two phase overvoltage elements are included. Phase
undervoltage/overvoltage protection can be set to operate when one, two, or three phases decrease
below the pickup level. When a four-wire voltage transformer connection is used, under/overvoltage
protection can be set for either phase-to-phase voltage or phase-to-neutral voltage. The 27P elements
are equipped with an undervoltage inhibit feature. Inverse or definite time can be selected.
Auxiliary Overvoltage (59X) Protection
Two auxiliary overvoltage elements provide overvoltage protection. Auxiliary overvoltage protection
elements can be set to monitor separately the third harmonic, neutral-shift, positive-sequence, negative-
sequence, or auxiliary fundamental voltages. Ground unbalance protection is provided when the auxiliary
voltage input is connected to a source of 3V0 such as a broken-delta VT or when 3V0 mode is selected to
obtain calculated offset voltage from the phase quantities. Inverse or definite time can be selected.
Frequency (81) Protection
Four independent frequency elements can be set for over, under, or rate of change (81R) frequency
operation. Each can be set separately to monitor the frequency on the main three-phase voltage input or
the Vx input. Rate of change can be set to operate on positive, negative, or “either”.
Note
BE1-11
m
protection systems enabled for IEC-61850 communication
(style Mxxxx5xxxxxxxx) have their frequency protection elements fixed
at two underfrequency elements and two overfrequency elements.
Instantaneous Undercurrent (37) Protection
One instantaneous undercurrent element operates with three-phase current. This protective function will
trip the motor when a loss of load occurs.
Instantaneous Overcurrent (50) Protection
Six instantaneous overcurrent elements can be set for single-phase, three-phase, ground, neutral,
positive-sequence, negative-sequence, or unbalanced protection.
Breaker Failure (50BF) Protection
One breaker failure function provides protection and security for the power system against failure of the
monitored breaker.
