Scope

This part of GB/T 17626 specifies the test method for the immunity of electrical and electronic equipment with a rated current of each phase less than or equal to 16A in the low-voltage power grid (50 Hz) to harmonics and inter-harmonics with a disturbance frequency up to 2kHz, and The range of basic test levels is presented. This section does not apply to electrical and electronic equipment connected to 16^2/3 Hz or 400Hz AC networks, the tests of equipment in these networks will be considered in other standards. The purpose of this standard is to establish a common benchmark for evaluating the low frequency immunity of electrical and electronic equipment to harmonics, interharmonics and grid signal frequencies. The test methods specified in this standard are general methods for evaluating the immunity of electrical and electronic equipment to harmonics, interharmonics and mains signal frequencies. GB/Z 18509-2001 specifies that this part is the basic standard for use by the professional standardization technical committee. The professional standardization technical committee has the right to decide whether to use this immunity standard. If it is determined to use this standard, it is responsible for determining the test level used and performance criteria. GB/Z 18509-2001 also indicates that the Electromagnetic Compatibility Standardization Technical Committee or its sub-committees will prepare to cooperate with professional standardization technical committees to formulate evaluation standards for special immunity tests of related products. Reliability qualification of electrical components (such as capacitors, filters, etc.) is not within the scope of this standard, nor does it consider long-term (more than 15 minutes) thermal effects. Recommended test ratings are well suited for residential, commercial and light industrial environments. For heavy industrial environments, the product committee is responsible for determining Class X, depending on the level required, and may also specify more complex waveforms as required. However, the proposed simple waveform has been observed in single-phase networks (where flat-topped waves are often seen in single-phase systems) and industrial networks (where sharp-topped waves are often seen in three-phase systems).
