SATEC provides new digital fault recording feature on BFM-11 feeder monitor

Global electrical utility supplier SATEC Inc. announced the addition of a powerful digital fault recording (DFR) feature to its Model BFM-11 Second Generation Branch Feeder Monitor.

SATEC is exhibiting at DistribuTECH International in booth 2769.

Designed specifically for electrical distribution substation applications, the DFR functionality provides substation engineers with critical information regarding relay tripping and reclosure operations, power disturbances and other system anomalies. The BFM-ll’s design allows it to easily and cost-effectively address much needed upgrades to older substations where existing in-service electromechanical devices are not capable of providing necessary detail to operate in today’s demanding digital smart grid environment. The addition of digital fault recording functionality greatly enhances essential system detail necessary for the analysis of power disturbances and at a price point unheard of in the industry for this level of functionality. The DFR feature monitors distribution network protection system performance utilizing multiphase waveform capture to immediately identify faults, failure of fault interrupting devices, incorrect tripping as well as to determine optimum tripping delay settings. Installation requires no interruption of CT circuits or disruption of service and an entire substation can be upgraded in a day or less. 

“With the inclusion of DFR functionality, The BFM-ll delivers both an important update to substation instrumentation and a valuable upgrade in performance,” said Juan Diaz, SATEC Utility Segment VP.  “Substation engineers can expect these new capabilities to have an immediate impact on their ability to dynamically monitor system performance and improve overall reliability”.

The BFM-II offers a range of important substation functions, including:

  • local and remote monitoring of breaker operations
  • local and remote supervision using digital and analog inputs
  • advance alerting of trips
  • long-term capture of trends and load profiles
  • communication via existing substation protocols such as DNP and IEC 60870
