Understanding Type Tests for Three-Phase Dry type transformers: What You Need to Know from a Chinese Manufacturer

Are you looking for a reliable Chinese manufacturer of three-phase Dry type transformers? If so, you need to understand the type tests that are used to ensure the quality of the transformers. In this blog post, we’ll explain what type tests are and why they’re important when selecting a Chinese manufacturer. Type tests are tests that are conducted on a transformer to ensure that it meets the required safety and performance standards. These tests are conducted by the manufacturer and are designed to evaluate the transformer’s electrical, mechanical, and thermal properties. The tests are conducted in accordance with international standards such as IEC 60076 and IEEE C57.12. The type tests for three-phase Dry type transformers include:

• Short-circuit test: This test is used to measure the short-circuit impedance of the transformer. It is conducted by applying a short-circuit current to the transformer and measuring the voltage drop across the terminals. • Temperature rise test: This test is used to measure the temperature rise of the transformer under normal operating conditions. It is conducted by measuring the temperature of the windings and core of the transformer. • Insulation resistance test: This test is used to measure the insulation resistance of the transformer. It is conducted by applying a voltage to the transformer and measuring the current that flows through the insulation.

• Dielectric test: This test is used to measure the dielectric strength of the transformer. It is conducted by applying a high voltage to the transformer and measuring the current that flows through the insulation. • No-load loss test: This test is used to measure the no-load loss of the transformer. It is conducted by measuring the power consumed by the transformer when it is not loaded. When selecting a Chinese manufacturer of three-phase Dry type transformers, it is important to ensure that they have conducted the necessary type tests to ensure the quality of their products. By understanding the type tests and their importance, you can be sure that you are getting a reliable and high-quality transformer from a reputable Chinese manufacturer.
