Transformer capacity and no-load load characteristic tester

With the development of China's power industry and the rapid increase in the use of distribution transformers, measuring transformer capacity and its true losses has become an urgent need for power supply enterprises. Our company combines years of on-site experience with practical experiencegoodThe digital technology has been carefully developed to create a new type of transformer capacity suitable for on-site use. This instrument is a device for testing and confirming power transformers, which can automatically determine the capacity and type of the transformer based on test data, and determine whether the transformer is a high energy consuming or energy-saving type based on the error between the transformer characteristic parameters and the standard. To meet the needs of investigating electricity theft and provide fast and reliable detection methods for electricity inspection departments. TR-DCSTransformer capacity and no-load load characteristic testerCapable of testing the capacity, no-load loss, and load loss of various models and specifications of oil immersed transformers, dry-type transformers, and special transformers with voltage levels of 6, 10, and 35KV, and capacity testing range from 30KVA to 40000KVA. The instrument adopts low voltage and low current testing method, which enhances the safety of testing work. At the same time, the built-in power supply can provide a large output power, ensuring the accuracy of test data and providing reliable signals for the testing of large capacity transformers. This instrument has a small size, light weight, simple wiring, easy operation, accurate measurement, good stability, and is easy to learn. It is a device for the electricity inspection department.

·Functional Features

1. The no-load test does not require an external power supply or voltage regulator, and can be completed using the built-in power supply.
2. For transformers without nameplates, there is no need to manually input any parameters, and the results can be automatically tested.
3. Large screen, high brightness, full temperature LCD display, all measurement data displayed on one screen, with Chinese information prompts. The LCD brightness and contrast can be adjusted, and it can display clearly even in strong light.
4. The tester is equipped with a built-in micro printer that can print and output Chinese characters, allowing for direct printing of test results on site.
5. There is a protective circuit inside to prevent instrument damage and personnel accidents.
6. Adopting long-life touch buttons, the operation is simple, and most of the operations can be done using default settings with just one click.
7. The built-in high-energy power supply can complete all testing projects, and during on-site testing, the instrument does not require an external power supply or auxiliary equipment such as voltage regulators and current boosters.
8. The power-saving mode ensures the completion of field testing for multiple transformers of various models.
9. Transformer capacity testing can be conducted at non rated connection positions.
10. The test data is stable and has good repeatability.
11. The wiring is simple, and testing can be completed with only two wire clamps. There is no phase difference in the testing, and you can choose any two phases.
12. The test data can be uploaded to a PC, which can print a formal test report and form a database for management.
