The various steps of the protocol for the measurement of partial discharges in such cables are carefully described. Details are given about the procedure for a sensor performance check, test setup preparation, and success criteria. The ultimate goal of this recommended practice is not verifying the compliance with any maximum acceptable limit of partial discharge amplitude, but rather focusing on the whole phenomenon of partial discharges, in order to assess whether critical partial discharges are present in the tested object (either a factory joint or a pre-molded joint of a HVDC extruded cable system). "Critical partial discharge" is used here to mean a discharge within the insulation of the object under test, excluding all external discharges that can be present during the ac voltage test, (e.g., corona discharges due to HV electrodes, conducting leads related to the test setup). 606 $aElectric discharges 606 $aPower electronics 615 0$aElectric discharges. 615 0$aPower electronics. 676 $a537.52 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a9910444458703321 996 $a2862-2020 - IEEE Recommended Practice for Partial Discharge Measurements under AC Voltage with VHF$92583953 997 $aUNINA LEADER 02995nam 22006493a 450 001 9910330348203321 005 20250709210447.0 010 $a9782709921695 010 $a2709921693 024 7 $a10.4000/books.irdeditions.29392 035 $a(CKB)4100000008622485 035 $a(OAPEN)1005180 035 $a(ScCtBLL)d328b96d-b11b-4380-905e-1744f69fb836 035 $a(FrMaCLE)OB-irdeditions-29392 035 $a(oapen)https://directory.doabooks.org/handle/20.500.12854/32397 035 $a(PPN)267949952 035 $a(FR-PaCSA)88876460 035 $a(FRCYB88876460)88876460 035 $a(Perlego)2327833 035 $a(EXLCZ)994100000008622485 100 $a20211214i20152019 uu 101 0 $afre 135 $auuuuu---auuuu 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aChangement climatique $eQuels de?fis pour le Sud ? /$fSerge Janicot, Magali Reinert 210 $cIRD Éditions$d2015 210 1$a[s.l.] :$cIRD E?ditions,$d2015. 215 $a1 online resource (1 p.) 311 08$a9782709918879 311 08$a2709918870 311 08$a9782709921688 311 08$a2709921685 330 $aLa mobilisation autour de la confe?rence Paris Climat 2015 (COP 21) a e?te? l'occasion de mettre en relief la vulne?rabilite? des milieux et des populations du Sud face au re?chauffement climatique.
