  • Page 8: Section 1 • General Information

    Breaker failure relays are applied on a per breaker basis. That is, one breaker failure relay for each breaker in the substation. BE1-BPR relay outputs must be arranged to initiate the tripping of all the circuit breakers necessary to isolate the fault if the protected circuit breaker fails to operate. The relay may also need to initiate transfer tripping of remote breakers to accomplish this task.

  • Page 9: Breaker Reclosing

    A third major factor to be considered in reclosing is supervisory control. Supervisory control allows the operator to maintain control of the system at all times. BE1-BPR relays have two supervisory inputs (WAIT and LOCKOUT). WAIT stops the reclose sequence at any point and allows the sequence to continue when the WAIT input is removed.

  • Page 10: Failed Breaker Operation Required Timing Information

    If left undetected, severe damage to the breaker contacts could result. BE1-BPR relays can detect this type of fault using an extra low level phase overcurrent pickup and a long moving average filter. These features have been provided as standard features in the BE1-BPR relays.

  • Page 11: Application - Enhanced Models

    Fault Recording Enhanced model BE1-BPR relays can also be configured to record and save digital fault data for all three phases plus neutral (0 to 200 amperes) and the digital state of each input and output contact. Analog waveforms are digitized by sampling the waveforms at a periodic rate and converting the measured signals to digital values.

  • Page 16: Section 2 • Application

    SECTION 2 • APPLICATION GENERAL BE1-BPR relays have seven inputs and five outputs plus an alarm output. There are three general purpose overcurrent fault detectors, six multipurpose timers, a three-shot recloser, and special outputs that are internally generated by the microprocessor. Using simple boolean expressions, the user can logically connect the various functional blocks to create a custom, application specific, logic scheme to handle special protection requirements.

    BFO, or to give an alarm. Breaker Resistor Protection Breaker resistor protection is a BE1-BPR relay feature that monitors the number of times a breaker opening resistor has been used and the amount of elapsed time between operations. If additional openings (operations) would exceed the resistor maximum power rating, the breaker resistor protection feature operates output 13 (O13), which can be used as a block reclose output.

  • Page 25: Breaker Failure Protection With Pre-Insertion Resistors

    This adaptive breaker failure logic can be configured by making use of the additional fault detectors and timers available in the BE1-BPR. One BF delay timer would be set to the maximum time allowed for the higher fault current level to be cleared and maintain system stability. The output would be ANDed with a fault detector set to detect this higher fault current level.
