Distribution network fault on LHC1 10/07/2011 F Duval, G Cumer on behalf of EN/EL 10/07/11

1) FACTS

- 3 major events in 30 min (11:03, 11:11, 11:34) - Discrimination not easy but last was worst (short on Verbois OHL) - Impact on several points (starting contact: EHT2 pulsed, Diesel network, Meyrin admin. loop) - False intertrip on MP7 (second in a row after 3 month of storms) - Autotransfer failed to refeed SEM12 (Io on couplers) 1) FACTS

- Situation after autotransfert 11:34:48 - All machines off - LHC loop and ATLAS partially off - MEYRIN reenergized from Swiss network - DIESEL generators started well on all LHC points - Situation after Piquet reconfiguration 13:50 - Piquet at work at 12:15 (difficult to understand) - fail to refeed loop from LHC2 ( Io) at 12:58 - LHC loop fed from LHC2 (in two steps) 13:28 - ATLAS fully refed at 13:49 - Network back to the standard configuration at 16:00 1) FACTS

2) ANALYSIS -Another false intertrip on MP7 - second in a row after 3 months of storm seasons - intertrip will be deactivated ASAP - Fiber optics will be installed for intertrips - Io twice attempting to reenergized SEM12 (LHC loop + ATLAS) -No explanation yet - Unexpected and complex situation for Standby service - 2h15 before renergizing LHC1 (too long)
