    BACKGROUND The T35 may be used on systems with breaker-and-a-half or ring bus configurations. In these applications, each of the two three-phase sets of individual phase currents (one associated with each breaker) can be used as an input to a breaker fail- ure element.

  • Page 86: Display Properties

    Some customers prefer very low currents to display as zero, while others prefer the current be displayed even when the value reflects noise rather than the actual signal. The T35 applies a cut- off value to the magnitudes and angles of the measured currents.

  • Page 88: Clear Relay Records

    Selected records can be cleared from user-programmable conditions with FlexLogic™ operands. Assigning user-program- mable pushbuttons to clear specific records are typical applications for these commands. Since the T35 responds to rising edges of the configured FlexLogic™ operands, they must be asserted for at least 50 ms to take effect.

  • Page 93 NUMBER: The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the UR over a network. The T35 operates as a TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file obtained from the T35 contains a list and description of all available files (event records, oscillography, etc.).
  • Page 94 THRESHOLD: 30000 The T35 supports the IEC 60870-5-104 protocol. The T35 can be used as an IEC 60870-5-104 slave device connected to a single master (usually either an RTU or a SCADA master station).

    See page 5–44. MESSAGE The T35 Transformer Management Relay has been designed to provide primary protection for medium to high voltage power transformers. It performs this function on a variety of power transformer configurations with up to six sets of three phase inputs available.

All CTs at the transformer are connected Wye (polarity markings pointing away from the transformer). User-entered settings in the relay characterizing the transformer being protected and allow the relay to automatically perform all necessary magnitude, phase angle, and zero sequence compensation.
  • Page 123 The reason the source phase sequence must be stated when describing the winding phase relationships is that these rela- tionships change when the phase sequence changes.

  • Page 124 Note that the delta winding currents leads the wye winding currents by 30°, (which is a type Yd11 in IEC nomenclature and a type Y/d330 in GE Multilin nomenclature) which is in disagreement with the transformer nameplate. This is because the physical connections and hence the equations used to calculate current for the delta winding have not changed.
  • Page 125 5 SETTINGS 5.3 SYSTEM SETUP The T35 automatically corrects for CT mismatch errors. All currents are magnitude compensated to be in units of the CTs of one winding before the calculation of differential and restraint quantities. The reference winding (w ) is the winding to which all currents are referred.
  • Page 126 The T35 performs this phase angle compensation and zero sequence removal automatically, based on the settings entered for the transformer. All CTs are connected Wye (polarity markings pointing away from the transformer).
