The transformer short-circuit impedance tester has significant importance in the power system, and its advantages mainly include the following aspects:
1. Simplified operation: Testers usually use low-voltage power supplies, one-time wiring, and do not require external voltage regulators, greatly simplifying the operation process and reducing the labor intensity of testers.
2. Lightweight and portable: Due to its small size and light weight, the tester is easy to carry to the site for testing, improving work efficiency.
3. Accurate measurement: Using the latest microcontroller testing technology and A/D synchronous AC sampling and digital signal processing technology to ensure the accuracy of measurement data. The tester has a storage function, which facilitates the storage and printing of data.
4. Defects discovered: Through testing equipment, defects such as winding displacement and deformation caused by severe fault currents during transportation, installation, and operation after factory testing can be found. This is crucial for ensuring the safe operation of transformers.
5. Safe and reliable: The tester has a complete protection circuit, strong anti-interference ability, high reliability, and ensures the safety of the testing process. Meanwhile, it is necessary to have professional technicians perform the operation to ensure the correct testing methods and reliable testing equipment.
6. Meeting standards: The purpose of conducting load tests is to measure the load loss and short-circuit impedance of transformers to determine whether their performance parameters meet the requirements of standards and technical agreements. The tester can accurately perform these measurements, helping to ensure that the transformer complies with relevant standards.
7. Comprehensive measurement: The tester can synchronously measure voltage, current, power, and measure the frequency of the applied power supply, while recording the applied voltage and current. This provides comprehensive testing data, which helps to evaluate the performance of transformers comprehensively.
8. Software upgrade and compatibility: Some transformer short-circuit impedance testers are equipped with RS-232 interfaces, which can be used for software upgrades or connected to PCs, enhancing the functionality and adaptability of the equipment.
9. High cost-effectiveness: Although the initial investment may be high, considering its improved work efficiency, reduced labor costs, and savings from preventing potential faults, the transformer short-circuit impedance tester has a good cost-effectiveness ratio.
In summary, the transformer short-circuit impedance tester plays an indispensable role in the field of power detection due to its simple operation, accurate measurement results, comprehensive testing functions, and high safety. It can not only help maintenance personnel discover and solve potential problems of transformers in a timely manner, but also improve the operational efficiency of transformers and extend their service life.
ZC-204B Transformer Short Circuit Impedance Tester is an instrument specifically designed for measuring low voltage short circuit impedance of transformers under on-site and laboratory conditions. The instrument comes with an adjustable power output, which is particularly suitable for on-site operation of 110kV and above main transformers. Short circuit impedance test is the most direct method to identify whether the winding of a transformer is deformed after being impacted by short-circuit current during operation or mechanical force during transportation and installation. It is of great significance for determining whether the transformer can be put into operation and is also one of the basis for determining whether disassembly inspection is required for the transformer.
