The previous versions of this document and the documents replaced are as follows. --- First published in.2007 as GB/T 18216.2-2007, first revised in.2012; ---This is the second revision.IntroductionIEC 60364-6 specifies the first test, continuous monitoring and adjustment of these equipment in TN, TT or IT systems. Standardized conditions for the post-adjustment test. In addition to the general standards that specify the implementation of these tests, IEC 60364-6 also includes To verify the requirements. Only in a few cases, such as when measuring insulation resistance, does IEC 60364-6 include the measuring device used. Details of the characteristics of the settings. Circuit diagrams given as examples in IEC 60364-6 and cited in the main text of the document are generally not applicable actual use. When dangerous voltages appear in the electrical installation and the equipment is improperly used or defective, the implementation of the test in the electrical installation can easily cause concern. outer. Therefore, in addition to simplifying the measurement, technicians also need to rely on measurement devices that ensure the safety of the measurement method. The application of the general safety rules for electrical and electronic measuring devices (IEC 61010-1) for protective measures is in itself insufficient. in Measurements in power installations are not only harmful to technicians, but also to third parties due to different measurement methods. Similarly, in order to obtain an objective judgment about the equipment, such as periodic tests, continuous insulation monitoring, or In the case of performance assurance, an important prerequisite is to use measurement devices from different manufacturers to obtain reliable and comparable measurement results. The purpose of GB/T 18216 is to specify uniform principles that are consistent with the above characteristics. These principles are applicable to nominal voltage AC Measuring and monitoring equipment for electrical safety test and performance test in 1000V and DC 1500V and below systems. GB/T 18216 It is proposed to consist of ten parts. ---Part 1.General requirements.
