Oil type transformer, with type test, China manufacturer

Understanding the Type Test Requirements for Oil type transformers from Chinese Manufacturers: What You Need to Know

Person 1: Hey, I’m trying to understand the type test requirements for Oil type transformers from Chinese manufacturers. Can you help me out? Person 2: Sure! Basically, the type test requirements for Oil type transformers from Chinese manufacturers are designed to ensure that the transformer meets the safety and performance standards set by the Chinese government. Person 1: What kind of tests are involved?

Person 2: Well, the tests typically include a dielectric test, a temperature rise test, a noise test, a short-circuit test, and a load test. The dielectric test is used to measure the insulation resistance of the transformer, while the temperature rise test is used to measure the temperature of the transformer under load. The noise test is used to measure the noise level of the transformer, while the short-circuit test is used to measure the short-circuit current of the transformer. Finally, the load test is used to measure the load capacity of the transformer. Person 1: Got it. So, what kind of results do these tests provide? Person 2: The results of these tests provide information about the safety and performance of the transformer. For example, the dielectric test results can tell you if the insulation of the transformer is adequate, while the temperature rise test results can tell you if the transformer is able to handle the load without overheating. The noise test results can tell you if the transformer is producing too much noise, while the short-circuit test results can tell you if the transformer is able to handle short-circuit currents. Finally, the load test results can tell you if the transformer is able to handle the load without any problems.
