    When contacting GE by e-mail, optionally include a device information file, which is generated in the EnerVista software by clicking the Service Report button. The service report also can be generated in the field, for example with a USB cable connected between the graphical front panel and a computer, and the Device Setup configured for the USB connection.

  • Page 15: Product

    2.1 Product description The B30 Bus Differential System is part of the Universal Relay (UR) series of products. It is a microprocessor-based relay that provides protection and metering for a busbar with up to six feeders. Protection is provided by a low impedance percent differential element with features that make it immune to current transformer (CT) saturation.

    IEC 61850, Modbus/TCP, TFTP, and PTP (according to IEEE Std. 1588-2008 or IEC 61588), and it allows access to the relay via any standard web browser (B30 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet port.

  • Page 18: Security

    When entering a settings or command password via EnerVista or any serial interface, the user must enter the corresponding connection password. If the connection is to the back of the B30, the remote password is used. If the connection is to a front panel port, the local password applies. (These two local and remote password settings are not shown the figure.)

    One role of one type is allowed to be logged in at a time. For example, one Operator can be logged in but not a second Operator at the same time. This prevents subsets of settings from being changed at the same time. B30 BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL...

    Replacement modules can be ordered separately. When ordering a replacement CPU module or front panel, provide the serial number of your existing unit. Not all replacement modules apply to the B30 relay. The modules specified in the order codes for the B30 are available as replacement modules for the B30.

Otherwise use the amperage of the active circuit connected to the contact input when its contact output is open and the voltage across the contact input is third trigger threshold to calculate the resistor value.

    Contact inputs can be susceptible to parasitic capacitance, caused by long cable runs affected by switching surges from external circuits. This can result in inadvertent activation of contact inputs with the external contact open. In this case, GE recommends using the contact I/O module with active impedance circuit.

    Selected records can be cleared from user-programmable conditions with FlexLogic operands. Assigning user- programmable pushbuttons to clear specific records is a typical application for these commands.

However, given that IEC 60870-5-103, IEC 60870-5-104, Modbus, and DNP are low-accuracy time synchronization methods, avoid their use for synchronization when better accuracy time protocols, such as IRIG-B and PTP, are active in the system.

    To provide the bus differential zoning as shown in the figures, eight currents need to be measured. Consequently, the protection cannot be accomplished by one B30. However, as each bus has not more than six connections, two B30s can be used.

  • Page 543: Dynamic Bus Replica

    This mechanism is referred to as a dynamic bus replica. The dynamic bus zone is programmed as a number of ‘source-status’ pairs. The Sources feature of the B30 is a convenient and flexible mechanism for associating input currents and voltages with protection and control elements.

  • Page 544: Ct Ratio Matching

    9.2.2 CT ratio matching The B30 allows for using CTs with various rated secondary currents and transformation ratios. Scaling to a common base is performed internally by the relay. The maximum allowable ratio mismatch is 32:1. For proper setting of the differential characteristic, it is imperative to understand the common base used by the relay.

    Figure 9-3: Biased operating characteristic The higher slope used by the B30 acts as an actual percentage bias regardless of the value of the restraining signal. This is so because the boundary of the operating characteristic in the higher slope region is a straight line intersecting the origin of the ‘differential - restraining’...

    LOW BPNT 9.3.3 Enhanced security To enhance the performance of the B30, the differential characteristic is divided into two regions having diverse operating modes, as shown in following figure. The first region applies to comparatively low differential currents and has been introduced to deal with CT saturation on low-current external faults.

  • Page 547: Directional Principle

    The B30 operates in the 2-out-of-2 mode in the first region of the differential characteristic. Both differential and directional principles (Differential Principle and Directional Principle) must confirm an internal fault in order for the biased differential element to operate.

The flag indicating whether the directional protection principle is satisfied is available as the FlexLogic...

  • Page 549: Saturation Detector

    9.5.1 CT saturation detection The saturation detector of the B30 takes advantage of the fact that any CT operates correctly for a short period of time, even under very large primary currents that would subsequently cause a very deep saturation. As a result, in the case of an external fault, the differential current stays very low during the initial period of linear operation of the CTs while the restraining signal develops rapidly.

  • Page 550: Output Logic And Examples

    For high differential signals, the directional principle is included only if demanded by the saturation detector (dynamic 1- out-of-2 / 2-out-of-2 mode). Typically, the directional principle is slower, and by avoiding using it when possible, the B30 gains speed.

  • Page 551: Internal And External Fault Example

    The first of the following figures presents the bus currents and the most important logic signals for the case of an external fault. Despite very fast and severe CT saturation, the B30 remains stable. The second figure presents the same signals but for the case of an internal fault. The B30 trips in 10 ms (fast form-C output contact).
