Tests not performed during transformer installation process include those related to insulation resistance.

While installing a transformer, there are a number of tests that need to be performed to ensure the safety and functionality of the equipment. However, there are certain tests that are not performed during the installation process.

One of the tests that is not typically performed during installation is the load test. This test is used to determine the actual capacity of the transformer by measuring its output under full load conditions. Load tests are typically performed in a controlled environment, such as a laboratory, and are not practical to conduct during the installation process.

Another test that is often skipped during installation is the impulse test. This test involves applying a high-voltage impulse to the transformer to simulate lightning strikes or other voltage surges. While this test is important for ensuring the transformer can withstand overvoltages, it is not typically performed during installation due to the complexity and equipment required.

Additionally, the temperature rise test is another test that is not typically performed during installation. This test involves measuring the temperature of the transformer under load conditions to ensure it does not overheat. While temperature rise tests are important for determining the long-term reliability of the transformer, they are typically conducted in a laboratory setting and not during installation.

While these tests are important for ensuring the safety and functionality of the transformer, they are not typically performed during the installation process. Instead, these tests are usually conducted in a controlled environment by trained professionals to ensure accurate and reliable results.

In conclusion, while installing a transformer, there are certain tests that are not typically performed due to the complexity and equipment required. While these tests are important for ensuring the safety and functionality of the equipment, they are best left to trained professionals in a controlled environment. By following proper testing procedures, you can ensure the transformer is installed correctly and will operate safely and efficiently.
