  1. 600 A ENERGY EXTRACTION SYSTEMSLS1 - COMMISSIONING

  2. Overview • 600 A Energy Extraction ; what, where, how ? • Introduction commissioning EE systems • Tunnel Test Teams • Individual Systems Tests • Short Circuit Tests • Hard-Ware Commissioning Tests • Planning

  3. Circuit with Energy Extraction

  4. Introduction Commissioning: Procedures to check, inspect and test every operational component - from individual functions; instruments and equipment, - up to complex modules, subsystems and systems. Before hand-over to Operations

  5. Circuit with Energy Extraction PIC BIC

  6. Availability of different systems Not all systems/modules available for commissioning at the same time: Commissioning split up in - Individual Systems Tests (IST) - Hard-Ware Commissioning Tests HWC IST: all tests which can be performed on one individual system (comparable with factory test) HWC: all tests with groups of systems

  7. TTT – Tunnel Test Teams 2 teams of each 2 test engineers - new collaborators from Krakow University (AGH) To be introduced in subject, 600A EE course and trained in 281 by Alexandre Erokhin and Gert Coelingh First sector 6-7 as “training-on-the-job” Tunnel Teams will be supervised by AE and GC during complete IST and HWC

  8. 600 A Energy Extraction B4IST Consolidation program to be completed: Just-in-time: Interface cards - software upgrade Exchange of Measurement PCB RQTL9 circuits in P3 and P7: Extraction Resistor Reduction to 0.4 Ω

  9. 600 A Energy Extraction IST IST tests: Visual Inspection grounding, dust, general state, wires etc. Insulation Test Disconnection of power cables – 1kV to gnd (delicate!! M16 Bolts and nuts - 180nm on top of Racks) Functional Tests Internal faults and interlocks Mechanical opening times of all breakers Verification of all commands (local + remote)

  12. 600 A Energy Extraction IST n.c. In case of non conformities: - Complete non-conformity sheet - Contact supervisor in case of showstopper All test results will be uploaded to dfs and checked by A. Erokhin on a daily basis

  13. 600 A Energy Extraction HWC HWC tests: Short Circuit Tests test warm part of circuit at ultimate current (only in cases where high current parts are changed) Interlock Test PIC Tests to control interlocks without current. Powering Tests PLI3.b1 & PNO.b1 Verification of connections and current sharing (voltage drops) Verification of opening time per system at intermediate current and nominal current Verification of contact resistance (voltage drops per phase)

  14. 600 A Energy Extraction SCT HWC tests: Short Circuit Tests test warm part of circuit at ultimate current (only in cases where high current parts are changed) Not all circuits are planned with SCT If SCT is performed some verifications can be done and powering tests with TTT reduced to PNO.b1 (opening time measurement) Price to pay: installation of SCT blocks on DFB level (EPC collaboration, planning etc) and another tunnel campaign

  15. 600 A Energy Extraction HWC HWC Powering testswith TTT presence Be extremely cautious / careful !!!!! High currents in s.c. circuits up to 1.5 H magnets Stored energies up to 150 kJ Not before JuneMid-August – Still time to increase awareness

  19. Planning 2014 • Individual System Tests - IST • February – June 2014 • 1wk / sector for 2 teams of 2 test-engineers • Hard-Ware Commissioning tests - HWC • June – December 2014 • 1wk / sector (PLI3.b1) & PNO.b1 for 2 teams of 2 test-engineers

  20. Realistic Planning 2014 • New Teams need: • All safety courses incl. “habilitation B1T, B2T or better BE (specific operations like measuring/testing) • To be trained and instructed • => Not available before end of February.. • First sector (point) might take 2 weeks • No impact on general planning • HWC (PNO.b1) with TTT • Duration strongly dependant on IEC/operators
