  2. Offline Analysis ±PCC.1 //Verify converter current to be +3.7A/+-0.6A 60seconds after the 1st crowbar activation (2nd PM) assertThat(I_MEAS).isEqualTo(+3.7, AMPERE).withinAbs(0.6, AMPERE) .at(60, SECOND).after(Occurrence.SECOND, PM_EVENT_TRIGGER); //Verify converter current & voltage decay is an exponential function with an absolute tolerance of 0.1A/0.05V starting 20ms after the 1st crowbar activation (2ndPM) assertThat(I_MEAS).isEqualTo(EXP).withinAbs(0.1, AMPERE) .starting(20, MILLI(SECOND)).after(Occurrence.SECOND, PM_EVENT_TRIGGER) .ending(150, SECOND).after(Occurrence.SECOND, PM_EVENT_TRIGGER); assertThat(V_MEAS).isEqualTo(EXP).withinAbs(0.1, VOLT)… … Using the eDSL Java Interfacepass criteria can be written in an easy to read/understand sentence form

  3. Automated Analysis Results ±PNO.d1 • 2011 HWC campaign • 1022 PNO.d1 tests on 750 60A-circuits • 69 consistency fails • 58 cases due to “just” failing decay criteria • 8 of which due to crowbar voltage • 2 current plateau checks failed • 93.2% of consistency! PNO.d1 Automated Analysis Results 2011 • Consistency check over previous campaigns resulted in discovering a faulty module(RCBV19.L5B1)that EPC were unaware of!

  4. Summary/Other work Framework and language clearlyusable by non-java experts! 60 A circuit offline analysis can now be fully automated (PCC1, PNO.d1) Will be ready for upcoming HWC campaign Other work: Expanding upon the analysis framework Working with Daniel/Bernhard on quench/heat diffusion simulations to devise more accurate thresholdsfor the main 13kA circuits Working with Arjan/Bernhard to create a “living document” for analysis procedures during HWC and beyond Automating online analysis of CSCM for upcoming HWC

  5. Thanks for listening!
