24、IEC 60060-1 and IEC 60060-2 cannot always 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
25、a commissioning procedure on equipment to 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 conditio
26、n to return to service; for diagnostic purposes, e.g. PD measurement, to demonstrate if the insulation is still free from dangerous defects, and as an indication of life expectation.

27、:00 2007, Uncontrolled Copy, (c) BSI 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 following on-site test voltages and in service stresses, which are in relation to IEC 60060-1: direct voltage; alternating
28、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: very low frequency voltage; damped alternating voltage. This standard is applicable to equipment with a highest voltag
29、e Um greater 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 relevant technical committee. For special applications, on-site test voltages different from those described in this st
30、andard 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 The selection of the test voltage levels should take the larger tolerances and measuring uncertainties into account. 2 N

36、pulse voltages on the 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

The behaviour of the insulation in this respect should be taken into account by the relevant technical committee when specifying the test procedures 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
46、 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 the leads required for connecting this device to the test object and the connections to earth, a transmission system connecting the output termin
47、als of the device to the indicating or recording instruments with its attenuating, terminating and adapting impedance or networks, and indicating or recording instruments together with any connections to the HV source. These components can be arranged in one compact unit together with the HV source.
48、 This usually applies to portable test equipment for medium-voltage apparatus. NOTE 2 Measuring systems which are based on non-conventional principles are acceptable if they meet the accuracy requirements specified in this standard. NOTE 3 The environment in which a measuring system functions, its c
