20、nts Replace the existing title of Annex A by the following: Annex A (normative) Minimum voltage levels Replace the existing title of Table A.1 by the following: Table A.1 Minimum spark-test voltages for cables having rated voltage (U0) between 300 V and 3 000 V 1 Scope Replace, in the second sentenc

21、e of the first paragraph, the term “single core cables“ by “single-core cables“. 3 Procedure Replace the existing third paragraph by the following: When used as an alternative to a voltage test in water, the test shall be restricted to layer thicknesses not greater than 2,0 mm unless otherwise speci

22、fied in the cable standard. Only the a.c. or d.c. voltage waveforms shall be used. Replace, in the fifth paragraph, the phrase “recommended voltages“ by “minimum voltages“. 62230 Amend. 1 IEC:2013 3 5 Test voltages Replace the existing fourth paragraph by the following: Where a cable standard states

23、 the test voltages, these shall be used. In the absence of such specified voltages, the test voltages given in Annex A shall be used. 6 Sensitivity 6.1 AC, d.c. and h.f. voltages Delete the second sentence of the first paragraph. Replace the existing text of the second paragraph with the following:

24、Equipment shall be capable of detecting the faults described in 6.1.1 and 6.1.2 and shall be verified according to 6.3. 6.1.1 AC and h.f. Replace the beginning of the existing text (“The typical fault is defined“) as follows: A fault is defined . 6.1.2 DC Replace the beginning of the existing text (

25、“The typical fault is defined“) as follows: A fault is defined . 6.2 Pulsed voltages Delete, in the first paragraph, the word “typical“. Replace the beginning of the second paragraph (“The typical fault is defined“) as follows: A fault is defined . 4 62230 Amend. 1 IEC:2013 Annex A Recommended minim

26、um voltage levels Replace the existing title and text of the annex as follows: Annex A (normative) Minimum voltage levels A.1 General The test voltages given in Table A.1 shall be used, unless the cable standard specifies alternative test voltages. The details of the test method are as given in the

27、main section of this standard. A.2 Test voltages A.2.1 General The voltages given in Annex A are the minimum levels to be used to locate defects in the layer under test. These levels shall only be reduced if specified in the relevant cable standard. NOTE Some countries have established higher test l

28、evels in their national standards. A.2.2 Contact electrodes The high-voltage supply to the test electrode may be a.c., d.c., h.f. or pulsed voltage, as specified in Clause 2 and 4.2. Table A.1 gives test voltages for cables having a rated voltage (U0) between 300 V and 3 000 V. 62230 Amend. 1 IEC:20

31、 bHF voltage testing for layer thicknesses greater than 1,0 mm shall be limited to frequencies between 500 Hz and 4 kHz. NOTE 1 The tabulated radial thickness is either the nominal thickness calculated in accordance with the relevant cable standard or the thickness specified in the constructional ta

32、ble of the relevant cable standard whichever is applicable. Pulsed voltage testing shall not be used for layer thicknesses greater than 2,0 mm. As a test to replace the traditional voltage test in water for single-core cables without any outer metallic layer, Table A.1 only applies for thicknesses n

33、ot greater than 2,0 mm and only the a.c. or d.c. voltage waveform shall be used. When testing laid-up core assemblies, i.e. cables without sheath, the test voltage level shall be that for the lowest individual insulation thickness in the assembly. NOTE 2 Particular cable standards may, in exceptiona

34、l circumstances (e.g. for sheathing materials known to exhibit low insulation resistance characteristics, i.e. Kiless than 100 M.km), require a reduction in the test voltage to ensure that excessive leakage current does not flow and give rise to spurious faults. In no instance will the reduction be

35、in excess of a factor of two and the fault detection system will be verified under the alternative test conditions. A.2.3 Non-contact electrodes The high-voltage supply to the test electrode shall be d.c. only, as defined in 4.2. The conductor of the core or the metallic layer under the sheath shall

36、 be continuously earthed and the potential difference between the electrode and the conductor or the metallic layer shall be 18 kV. _ 6 62230 Amend. 1 CEI:2013 AVANT-PROPOS Le prsent amendement a t tabli par le comit dtudes 20 de la CEI: Cbles lectriques.
