  • Page 15: Product Description

    2.1.1 Overview 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.
  • Page 16 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. The Ethernet port also supports the Parallel Redundancy Protocol (PRP) of IEC 62439-3 (clause 4, 2012) when purchased as an option.

    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 477: 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 operand BUS 1(2) DIR.
  • Page 479: 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 480: 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.
