1180-2 © I EC:1994– 5 –INTERNATIONAL ELECTROTECHNICAL COMMISSIONHIGH-VOLTAGE TEST TECHNIQUES FORLOW-VOLTAGE EQUIPMENT -Part 2: Test equipmentFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardizationcomprising all national electrotechnical committees (IEC National Committees). The object of the IEC is topromote international cooperation on all questions concerning standardization in the electrical andelectronic fields. To this end and in addition to other activities, the IEC publishes International Standards.Their preparation is entrusted to technical committees; any IEC National Committee interested inthe subject dealt with may participate in this preparatory work. International, governmental andnon-governmental organizations liaising with the IEC also participate in this preparation. The IECcollaborates closely with the International Organization for Standardization (ISO) in accordance withconditions determined by agreement between the two organizations.2)The formal decisions or agreements of the IEC on technical matters, prepared by technical committees onwhich all the National Committees having a special interest therein are represented, express, as nearly aspossible, an international consensus of opinion on the subjects dealt with.3)They have the form of recommendations for international use published in the form of standards, technicalreports or guides and they are accepted by the National Committees in that sense.4)In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.International Standard IEC 1180-2 has been prepared by IEC technical committee 42:High-voltage testing techniques.The text of this standard is based on the following documents:DISReport on voting

1180-2 © I EC:1994– 7 –HIGH-VOLTAGE TEST TECHNIQUES FORLOW-VOLTAGE EQUIPMENT -Part 2: Test equipment1 ScopeThis part of IEC 1180 is applicable to the test equipment used for dielectric tests onlow-voltage equipment. It covers tests with direct, alternating or impulse voltage, impulsecurrent, and tests with a combination of impulse voltage and impulse current. Verificationprocedures necessary for ensuring that the dielectric tests comply with the voltage, orcurrent, requirements stated in part 1 of this standard in shape and magnitude are stated.The test equipment comprises a voltage and/or current generator and a measuringsystem. This standard covers test equipment in which the measuring system is protectedagainst external interference and coupling by appropriate screening, for example a continu-ous conducting shield. Therefore, simple comparison tests are sufficient to ensure validresults.Test equipment having measuring systems composed of non-screened components and/orconnected by long leads is not covered in this standard. In this case guidance can beobtained from IEC 60-2 keeping in mind the less stringent requirements of this standard.2 Normative referencesThe following normative documents contain provisions which, through reference in thistext, constitute provisions of this part of IEC 1180. At the time of publication ofthis standard, the editions indicated were valid. All normative documents are subject torevision, and parties to agreements based on this part of IEC 1180 are encouragedto investigate the possibility of applying the most recent editions of the normativedocuments indicated below. Members of IEC and ISO maintain registers of currently validInternational Standards.IEC 68-1: 1988, Environmental testing – Part 1: General and guidanceIEC 790: 1984, Oscilloscopes and peak voltmeters for impulse testIEC 1083-1: 1991, Digital recorders for measurements in high-voltage impulse tests –Part 1: Requirements for digital recordersIEC 1180-1: 1992, High-voltage test techniques for low-voltage equipment – Part 1: Defi-nitions, test and procedure requirementsNOTE – The requirements of IEC 790 and IEC 1083-1 may be reduced because the uncertainty limitsof this part of 1180 are less stringent than those in IEC 60-1, for example, ±5 % for peak value (±3 %in IEC 60-1).SIST EN 61180-2:1998
1180-2 © IEC:1994- 9 -3 DefinitionsFor the purpose of this International Standard, the following definitions apply.3.1 test equipment: Complete set of devices needed to generate and measure the testvoltage or current applied to a test object.3.2 reference measuring system: Measuring system having sufficient accuracy andstability for it to be appropriate for use in the approval of other systems by making simul-taneous comparative measurements of specific types of wave-form and ranges of voltageor current.NOTE — Uncertainty limits are given in clause 10.3.3 measuring error: Difference between the value measured by the test equipment andthe value given by the reference measuring system (reference value). It is usuallyexpressed as a percentage of the reference value.3.4 conventional output impedance (impulse voltage generator): Value of [(Voc -VR)/ VR] R where Voc is peak output voltage into an open circuit and VR is the voltage ona resistive load R where R is suc
