22、be achieved during on-site tests, due to a variety of external factors not present in factory and laboratory tests such as external electric and magnetic fields, weather conditions, etc. On-site high-voltage tests are required: as withstand tests as part of a commissioning procedure on equipment to

23、demonstrate that transport from manufacturer to site, and the erection on-site complies with manufacturers specification; as withstand tests after on-site repair, to demonstrate that the equipment has been successfully repaired, and is in a suitable condition to return to service; for diagnostic pur

24、poses, e.g. PD measurement, to demonstrate if the insulation is still free from dangerous defects, and as an indication of life expectation. EN 60060-3:2006 6 HIGH-VOLTAGE TEST TECHNIQUES Part 3: Definitions and requirements for on-site testing 1 Scope This part of IEC 60060 is applicable to the fol

25、lowing on-site test voltages and in service stresses, which are in relation to IEC 60060-1: direct voltage; alternating voltage; lightning impulse voltage of aperiodic or oscillating shape; switching impulse voltage of aperiodic or oscillating shape. For special tests the following voltages are used

26、: very low frequency voltage; damped alternating voltage. This standard is applicable to equipment with a highest voltage Umgreater than 1 kV. The selection of on-site test voltages, test procedures and test voltage levels for apparatus, equipment or installations is under the responsibility of the

27、relevant technical committee. For special applications, on-site test voltages different from those described in this standard may be specified by the relevant technical committee. NOTE 1 The different voltage waveforms listed above do not necessarily provide equal stress on the test object. NOTE 2 T

28、he selection of the test voltage levels should take the larger tolerances and measuring uncertainties into account. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated refe

29、rences, the latest edition of the referenced document (including any amendments) applies.

30、on Part 1: Definitions, principles and rules 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. For all other definitions relating to testing procedures, see IEC 60060-1, and for those relating to measuring systems, see IEC 60060-2. Definitions of p

31、arameters are given in the relevant clauses of this standard. 3.1 on-site test test at the place of use of the apparatus, equipment or installation that is to be tested, and with the test object as far as possible in its service condition EN 60060-3:2006 7 3.2 impulse voltage intentionally applied a

32、periodic or oscillating transient voltage, which usually rises rapidly to a peak value and then its enveloping curve falls more slowly to zero (IEC 60060-1:1989, Term 3, modified) 3.3 lightning and switching impulse voltages a distinction is made between lightning and switching impulse voltages on t

33、he basis of duration of the front. Impulses with front duration up to 20 s are defined as lightning impulse voltages and those with longer fronts are defined as switching impulse voltages Generally, switching impulse voltages are also characterized by total durations considerably longer than those o

34、f lightning impulse voltages. (IEC 60060-1:1989, Term 3.1) 3.4 characteristics of the test voltage those characteristics specified in this standard for designating the different types of voltage excursion that define the test voltage (IEC 60060-1:1989, Term 4.2) 3.5 prospective characteristics of a

35、test voltage the characteristics which would have been obtained if no disruptive discharge had occurred. When a prospective characteristic is used, this shall always be stated (IEC 60060-1:1989, Term 4.2.1) 3.6 actual characteristics of a test voltage characteristics that occur during the test at th

36、e terminals of the test object (IEC 60060-1:1989, Term 4.2.2) 3.7 value of the test voltage as defined in the relevant clauses of the present standard (IEC 60060-1:1989, Term 4.2.3) 3.8 classification of insulation in test objects insulation systems of apparatus and high-voltage structures must basi

37、cally be classified into self-restoring and non-self-restoring insulation and may consist of external and/or internal insulation (IEC 60060-1:1989, Term 5) 3.8.1 external insulation distances in atmospheric air, and the surfaces in contact with atmospheric air of solid insulation of the equipment wh

38、ich are subject to dielectric stresses and to the effects of atmospheric and other external conditions such as pollution, humidity, vermin, etc. (IEC 60071-1:1993, Term 3.2) EN 60060-3:2006 8 3.8.2 internal insulation internal solid, liquid or gaseous insulation, which are protected from the effects

39、 of atmospheric and other external conditions (IEC 60071-1:1993, Term 3.3) 3.8.3 self-restoring insulation insulation that completely recovers its insulating properties after a certain time interval following a disruptive discharge caused by the application of a test voltage (IEC 60071-1:1993, Term

40、3.4, modified) 3.8.4 non-self-restoring insulation insulation that loses its insulating properties, or does not recover them completely, after a disruptive discharge caused by the application of a test voltage (IEC 60071-1:1993, term 3.5, modified) NOTE In high-voltage apparatus, parts of both self-

41、restoring and non-self-restoring insulation often operate in combination and some parts may be degraded by repeated or continued voltage applications. The behaviour of the insulation in this respect should be taken into account by the relevant technical committee when specifying the test procedures

42、to be applied. 3.9 measuring systems and their components 3.9.1 measuring system complete set of devices suitable for performing a high-voltage measurement (IEC 60060-2:1994, Term 3.1.1, modified) NOTE 1 A measuring system is usually comprised of the following components: a converting device with th

43、e leads required for connecting this device to the test object and the connections to earth, a transmission system connecting the output terminals of the device to the indicating or recording instruments with its attenuating, terminating and adapting impedance or networks, and indicating or recordin

44、g instruments together with any connections to the HV source. These components can be arranged in one compact unit together with the HV source. This usually applies to portable test equipment for medium-voltage apparatus. NOTE 2 Measuring systems which are based on non-conventional principles are ac

45、ceptable if they meet the accuracy requirements specified in this standard. NOTE 3 The environment in which a measuring system functions, its clearances to live and earthed structures and the presence of electric or magnetic fields may significantly affect its accuracy. 3.9.2 record of performance o

46、f a measuring system detailed record, established by the user, describing the system and containing evidence that the requirements given in this standard have been met. This evidence shall include the results of the initial acceptance test and the schedule and results of each subsequent performance

47、test and performance check (IEC 60060-2:1994, Term 3.1.2) 3.9.3 approved measuring system a measuring system that is shown to comply with the requirements of this standard by: an initial performance test; successive performance checks and performance tests; inclusion of the results of these tests in

48、 the record of performance. EN 60060-3:2006 9 The system is approved only for the arrangements and operating conditions included in its record of performance (IEC 60060-2:1994, Term 3.1.3, modified) 3.9.4 reference measuring system measuring system having sufficient accuracy and stability for use in

49、 the approval (calibration) of other systems by making simultaneous comparative measurements with specific types of waveform and ranges of voltage or current (IEC 60060-2:1994, Term 3.1.4) NOTE A reference measuring system (maintained in accordance with the requirements of IEC 60060-2:1994) can be used as an approved measuring system but the converse is not true. 3.9.5 converting device device for converting the high voltage to be measured into another quantity, compatible with the ind
