Periodic Testing
Periodic testing can be performed at regularly scheduled intervals or upon an indication of problems or
questionable operations within the BE1-11m. Verifying the integrity of the protection system’s
performance, short of playback of recorded events, may be necessary by performing certain tests similar
to those accomplished in the
Acceptance Testing chapter. Verification that the BE1-11m is measuring
signals faithfully, that BE1-11m logic is appropriate, and that protective elements and equipment (main or
auxiliary) operate correctly are goals that can be achieved during this type of testing.
Basler Electric recommends that all captured fault records and sequence of event records be analyzed
and kept on file as in-service periodic test results for this particular device. This is an indication that all
protective elements and the associated equipment are operating satisfactorily.
It is not the intent of this manual to elaborate on every conceivable test possible because this would
encroach on individual preferences, techniques, and philosophies. It is the intent to pursue relevant
testing methods to verify this BE1-11m meets published design specifications and applicability.
Functional Testing
Functional (or application) testing is significantly more comprehensive in nature and tests suitability for a
particular application. Functional testing also provides a means to familiarize the user with the logic and
operation of this device. Test setups are generally more involved and often include ancillary equipment
beyond voltage or current source type equipment. While economics may at times prohibit full functional
testing, it is recommended that some functional testing be performed when published specifications lack
appropriate detail to satisfy application testing requirements.
Basler Electric performs a thorough and comprehensive functional test of all protection systems before
shipping. This ensures that this device is within specified tolerances, measures accurately, and operates
correctly as designed.
Testing and Troubleshooting Aids
Under test or in-service, the BE1-11m provides several ways to check operations, targets, or events. The
status of the system is monitored by a continuous self-test. The most basic reporting function is targets.
Targets can be viewed through BESTCOMSPlus
® or the front-panel display. Fault Summary Reports,
Sequence of Events Recorder (SER) Reports, and Oscillographic Records yield more detail.
Each time a system disturbance occurs in or around this BE1-11m zone of protection, it is a test of the
BE1-11m performance during the fault. If a questionable operation results in the need for troubleshooting,
you have several ways in which to troubleshoot the BE1-11m, the installation, and overall application.
Performance Testing
Performance testing can be accomplished through the capture and playback of system fault records. In
actual applications, this type of test realizes further confirmation of faithful BE1-11m responses during
system disturbances. For specific power system disturbances, protection systems can be subjected to a
re-creation of captured events with the aid of equipment capable of replicating COMTRADE record files.
In these instances, there is significant merit in testing protection systems in this manner to assess
BE1-11m performance. Correct response of BE1-11m action in a performance test is supplemental
verification of the conclusions drawn from functional (or application) tests.
This type of testing verifies not only whether the device operated correctly for a particular system
disturbance but also offers additional confirmation of your protection philosophy in this application. It is
beyond the scope of this manual to develop performance tests for this device. For assistance in
developing these types of tests, please consult Basler Electric and your test equipment.
