High frequency recommended vocabulary
The Chinese part of the EMC test series covering the disturbance of high current equipment is applied in China to the heavy industrial products that dominate parts of the manufacturing sector: large variable speed drives for pumps and fans, the converters used in metallurgy and in cement production, welding equipment and the plant installed in the rapidly built industrial parks. Because the test requires a generator capable of supplying the full load current of the product while changing the applied voltage quickly, it is performed in China by the larger laboratories and by the test facilities of the major equipment manufacturers themselves. The requirement is imposed through the Chinese product standards for adjustable speed electrical power drive systems and through the technical specifications of industrial customers. The Chinese text corresponds to the international document, and this page identifies the Chinese designation under which the test will be specified by a domestic customer.
