Tip Test and Measuring Audible Noise Level are vital procedures in the transformer industry for determining quality and performance. Trans – El, a leading transformer manufacturer, incorporates these two tests as integral parts of their standard production procedures, thereby guaranteeing the quality and reliability of the products they offer to their customers.
The Tip Test is a comprehensive test used to verify the compliance of a transformer model with specified technical and operational requirements. This test is typically conducted on a prototype model and encompasses various sub-tests.
These sub-tests often include dielectric strength tests, temperature rise tests, short-circuit withstand tests, and mechanical endurance tests, among others. Successfully passing all these tests confirms that the respective transformer model adheres to technical and performance requirements.
Measuring the audible noise level determines how much noise a transformer will produce during operation. The noise level generated during operation must be within the limits set by environmental regulations. Additionally, considering that transformers are often installed in densely populated areas or residential zones, controlling noise levels is of significant importance in preventing potential noise pollution issues.
Trans – El incorporates both the Tip Test and the measurement of audible noise level as part of their production processes. This ensures that Trans – El transformers meet the highest standards in both technical and operational aspects.
As a result, Trans – El not only provides high-quality and reliable transformers to its customers but also fulfills its environmental responsibilities. This demonstrates that at every stage of the production process, Trans – El prioritizes quality and reliability, offering complete assurance to customers regarding the quality and reliability of their products.
The Importance and Process of the Tip Test
The Tip Test and measuring audible noise level are essential tests that we, Trans – El, utilize to guarantee the quality and reliability of our products. Each transformer model we produce undergoes these tests, and this process serves as evidence that our products conform to industry standards and customer expectations.
The Tip Test is used to assess the technical specifications and performance of a transformer model. This test covers many critical parameters, such as load and no-load losses, current, voltage, frequency, and phase differences.
Additionally, the test evaluates the transformer’s performance under conditions like heating, dielectric performance, and short-circuit scenarios. The Tip Test confirms whether each transformer model adheres to specified technical specifications and helps detect any errors in the manufacturing process, material defects, or design flaws.
Measuring the audible noise level determines how much noise a transformer will generate during its operation. Controlling noise levels is essential for improving user experience and minimizing environmental impacts.
As Trans – El, we prove our commitment to delivering high-quality, reliable, and user-friendly transformers through tests like the Tip Test and measuring audible noise levels. These tests not only serve as quality control mechanisms but also enhance the value of the service we provide to our customers.
Measuring Audible Noise Level
Measuring the audible noise level is an integral part of our commitment, as Trans – El, to providing high-quality transformers with superior quality and functionality.
Measuring the audible noise level is particularly important to determine how much noise our transformers generate during operation. This is crucial for maintaining both user comfort and minimizing our environmental footprint.
To conduct this test, specific points around the transformer are initially identified. For ONAN (Oil Natural Air Natural) cooling mode, measurements are taken at distances of 0.3m from the casing, and for ONAF (Oil Natural Air Forced) cooling mode, measurements are taken at 2m distances. The distance between these points should not exceed one meter.
Once these markings are completed, the transformer is energized to its nominal voltage, and a noise level measurement device is used at the designated points. This device ensures accurate and precise measurement of the noise produced by the transformer.
The microphone’s height above the ground depends on the transformer’s top cover level. For transformers with cover levels up to 2.5 meters, the microphone height should be half the height of the cover level. For taller transformers, measurements are taken at heights corresponding to 1/3 and 2/3 of the cover level. If the transformer features an ONAF forced cooling system, measurements are also conducted along the perimeter at a distance of 2 meters from the main body.
Measuring the audible noise level is a test that guarantees the quality of our products. By providing transformers with low noise levels to our customers, we aim to enhance their experiences and satisfaction. Additionally, this measurement demonstrates that Trans – El produces products that adhere to quality standards and showcases the meticulousness with which we work to ensure customer satisfaction.
