Except for the following normative references, this chapter of GB/T 19212.1-2016 applies. The following reference documents are added to this chapter: GB/T 19212.1-2016 "Safety of Transformers, Reactors, Power Supply Devices and Their Combinations - Part 1: General Requirements and Tests" (IEC61558-1:2009, MOD). In addition to the following terms and definitions, this chapter of GB/T 19212.1-2016 is applicable A transformer with an unrestricted transformer ratio and adjusted by moving the brush position along a continuous path along the exposed winding. The input and output voltages of the variable auto transformer come from a common winding regulator. The following terms and definitions have been added to the general term: a device used by a brush current collector to transmit current from a point on the contact path to a sliding contact component located on a terminal or bushing. A mechanical device used to drive a brush. Fixed winding is a winding or part of a winding that cannot change the transformer ratio. Variable winding has a winding or winding part that is used to change the contact path of the transformer ratio. The following modifications are made to the rated value clause: Not applicable. The following terms and definitions are added to this article: rated output voltage range The output voltage range of a "transformer" or power supply device provided by the manufacturer under the conditions of rated power supply voltage, rated power supply frequency, rated output current, and rated power factor (for multiphase "transformers" and power supply devices, phase to phase voltage)
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
