Scope

This part of GB/T17626 specifies the immunity requirements, test methods and recommended test level range for equipment to unipolar surge (shock) caused by switching and lightning transient overvoltage, and specifies the requirements for different environments and installation conditions. The next few test levels. The requirements set out in this standard apply to electrical and electronic equipment. The purpose of this section is to establish a common benchmark for evaluating the performance of electrical and electronic equipment when subjected to surges (shocks). This standard specifies a consistent test method to assess the immunity of equipment or systems to specified phenomena. Note: As stated in IEC Guide 107, this part is the basic standard for electromagnetic compatibility for use by product committees. IEC Guide 107 also stipulates that the product committee is responsible for determining whether to apply this immunity test standard and, if used, for determining the appropriate test level and performance criteria. The National Electromagnetic Compatibility Standardization Technical Committee and its sub-committees are willing to cooperate with product committees to evaluate the special immunity requirements of their products. This section specifies: --- the range of test levels; --- test equipment; --- test configuration; --- test procedures. The task of the laboratory test is to find out the reaction of the equipment to the surge (impulse) voltage generated by the switch or lightning under the specified working state. This section does not test the insulation capability of the EUT withstanding high voltage. This section does not consider the direct injection of lightning current for direct lightning strikes. 0.0050 unit PDFa factor u(xi )μs triangle 2. range 40 50 unit PDFa factor u(xi )μs·kHz rectangle 1.73 23. range 0.0075 unit PDFa factor u(xi )ci unit ui (y) unit V triangle 2. range 0.0050 1.4 50 Unit PDFa Factor u(xi )μs Trigonometric 2.
