Power transformers are sensitive to temperature, humidity, and boost speed, which can affect their performance. Temperature affects test results due to the insulation resistance of the transformer, while humidity increases air moisture content, affecting detection accuracy. The speed of voltage boosting also affects transformer operation, with leakage current causing deviations from theoretical values. These factors, particularly in large-capacity transformers, require attention to ensure accurate test results and prevent out-of-control results.
1) Temperature effect.
Power transformers have a certain sensitivity to temperature. There are bound to be certain differences in test results caused by different external ambient temperatures. In particular, the specific materials that make up the power transformer have a more prominent impact on temperature. As the temperature increases during the test, the insulation resistance of the high-voltage transformer will decrease, which will have a greater impact and threat to the test results.
(2) Effect of humidity.
For power transformer testing, the influence of humidity is also an important aspect. The influence of humidity mainly refers to the increase in air moisture content caused by humidity, which in turn affects the detection accuracy of power transformers. That is, it is difficult to obtain more accurate data information during the test process, which will inevitably lead to out-of-control test results.
(3) Effect of boost speed.
There are many reasons for problems in the operation of high-voltage transformers. They are not only affected by the influence and interference of temperature and humidity in the external environment, but are also affected to a large extent by the operating conditions of the high-voltage transformer. For example, the speed of voltage boosting will affect the operation of the transformer. Leakage current has a certain impact, resulting in a significant deviation from the theoretical value. This problem and impact mechanism are most obvious in large-capacity transformers and require sufficient attention.
