29、nts for digital recorders. Digital recorders, like analogue oscilloscopes, are susceptible to changes in their characteristics. However, the more stringent testing (than is practical for analogue oscilloscopes) specified for digital recorders for standard impulse voltage and current measurement has

30、led to the accuracy of digital recorders being more clearly demonstrated. This part of IEC 61083 applies to software used to process digital records to provide the values of the relevant impulse parameters. The raw data are retained for comparison with the processed data. However, since the paramete

31、rs of the test impulse (including the test value) are to be read from the processed data, it is important to establish tests to ensure that the reading of parameters is adequately performed. The problem is how to ensure this, while permitting users to develop a wide range of techniques. This problem

32、 is further complicated by the different needs of various users, ranging from single-purpose test laboratories, for example those of a cable manufacturer who may only test a few objects which are capacitive, to large high-voltage test/research laboratories, which may perform tests on a very wide ran

33、ge of objects, which have a correspondingly wide range of impedances. The approach taken in this part of IEC 61083 is to provide, from a test data generator software, waveforms (and ranges of their parameters) which a user can employ to verify that a procedure gives values within the specified range

34、s. To reduce the amount of testing required, the waveforms are divided into groups, and the user needs only to check those groups that are appropriate for the high-voltage and/or high-current tests to be performed in his/her laboratory. New definitions for lightning impulse parameters and switching

35、impulse time-to-peak evaluation are introduced in IEC 60060-1. The changes in these definitions have lead to significant changes in some of the reference values in this standard. The number of impulse records in the test data generator has been increased to cover a wider range of impulse shapes seen

36、 in on-site testing. BS EN 61083-2:2013 6 61083-2 IEC:2013 INSTRUMENTS AND SOFTWARE USED FOR MEASUREMENT IN HIGH-VOLTAGE AND HIGH-CURRENT TESTS Part 2: Requirements for software for tests with impulse voltages and currents 1 Scope and object This part of IEC 61083 is applicable to software used for

37、evaluation of impulse parameters from recorded impulse voltages and currents. It provides test waveforms and reference values for the software required to meet the measuring uncertainties and procedures specified in IEC 60060-1, IEC 60060-2, IEC 60060-3 and IEC 62475. Hardware with built-in firmware

38、 that cannot accept external numerical input data is not covered by this standard. The object of this standard is to establish the tests which are necessary to show that the performance of the software complies with the requirements of the relevant IEC standards; define the terms specifically relate

39、d to digital processing; specify reference values and the acceptance limits for the reference impulses; specify the requirements for the record of performance; define the methods to assess the contribution of software to the measurement uncertainty. 2 Normative references The following documents, in
