  • Page 179 ABB protection relays are preferable tested by aid of components from the COMBITEST testing system described in information B03-9510 E. Main components are RTXP 8/18/24 test switch located to the left in each protection relay and RTXH 8/18/24 test handle which is inserted in test switch at secondary testing.
  • Page 180 Periodic maintenance tests Chapter 12 Commissioning and maintenance of the fault clearing system 3.2.6 Trip circuit check When the protection IED undergoes an operational check, a tripping pulse is normally obtained on one or more of the output contacts and preferably on the test switch. The healthy circuit is of utmost importance for the protection operation.

    IED and measuring circuitry may be damaged. An alternative is to open the IED and send only the faulty circuit board to ABB for repair. When a printed circuit board is sent to ABB, it must always be placed in a metallic, ESD-proof, pro- tection bag.
  • Page 187 Repair instruction Chapter 13 Fault tracing and repair If the REx670 IED has the increased measuring accuracy feature (Optional), a file with unique calibration data for that particular transformer module is stored in the Main processor module. Therefore it is not possible to freely change only one of these modules with maintained accuracy. To maintain the accuracy feature the calibration file stored in the NUM must match the TRM and ADM used together with the NUM.

TCP/IP was developed by DARPA for internet working and encompasses both net- work layer and transport layer protocols. While TCP and IP specify two protocols at specific protocol layers, TCP/IP is often used to refer to the entire US Department of Defense protocol suite based upon these, including Telnet, FTP, UDP and RDP.
