As a China manufacturer, it is important to understand the type tests for Oil immersed transformers. These tests are designed to ensure that the transformer meets the required safety and performance standards. In this guide, we will explain the different types of tests and how they are used to evaluate the quality of the transformer.
The first type of test is the dielectric test. This test is used to measure the insulation resistance of the transformer. It is done by applying a high voltage to the transformer and measuring the current that flows through it. The higher the insulation resistance, the better the transformer will be able to withstand electrical shocks and other hazards.
The second type of test is the short-circuit test. This test is used to measure the ability of the transformer to withstand short-circuits. It is done by applying a high current to the transformer and measuring the voltage that is generated. The higher the voltage, the better the transformer will be able to withstand short-circuits.
The third type of test is the temperature rise test. This test is used to measure the temperature rise of the transformer when it is operating. It is done by measuring the temperature of the transformer at different points in its operation. The higher the temperature rise, the better the transformer will be able to withstand high temperatures.
Finally, the fourth type of test is the overload test. This test is used to measure the ability of the transformer to withstand overloads. It is done by applying a high current to the transformer and measuring the voltage that is generated. The higher the voltage, the better the transformer will be able to withstand overloads.
