The transformer short-circuit impedance tester has a wide range of applications, mainly used in the following fields and scenarios:
1. Production and Quality Control of Power Transformers
① Factory testing: Before the transformer leaves the factory, a strict short-circuit impedance test is conducted using a short-circuit impedance tester to ensure that the transformer meets the design requirements and technical specifications.
② Quality monitoring: During the production process of transformers, product quality is monitored by measuring short-circuit impedance to improve product reliability and customer satisfaction.
2. Maintenance and Fault Analysis of Power Transformers
① Routine maintenance: In the routine maintenance of transformers, deformation and insulation aging issues of windings are detected in a timely manner by measuring short-circuit impedance, preventing potential equipment failures and ensuring the stable operation of the power system.
② Fault analysis: When a transformer malfunctions, a short-circuit impedance tester can be used to diagnose the cause of the fault, especially for the situation after short-circuit current surge. By comparing the impedance value changes before and after testing, it can determine whether the winding has shifted or deformed.
3. Equipment installation and debugging
① New equipment installation: During the installation of new equipment, use a short-circuit impedance tester to verify whether the installation of the transformer complies with electrical specifications, ensuring that the newly installed transformer has normal working conditions.
② Equipment maintenance: After transformer maintenance, verify through testing whether the performance of the repaired transformer has returned to normal.
4. Security certification and technical evaluation
① Safety certification: During the safety certification of transformers, short-circuit impedance testers provide necessary data support to assist certification agencies in evaluating whether the safety performance of transformers meets national or international safety standards.
② Technical evaluation: Before trading or leasing second-hand equipment, use a short-circuit impedance tester to conduct a technical evaluation of the transformer to ensure its normal performance and avoid risks caused by poor equipment performance during the transaction process.
5. Other application scenarios
① Transformer selection and design verification: During the transformer selection or design verification phase, the performance parameters of the transformer are evaluated through short-circuit impedance testing to ensure the rationality of the selection or design.
② Teaching and Research: In universities or research institutions, short-circuit impedance testers can be used for teaching experiments or research work related to transformers, providing accurate testing data support.
In summary, the transformer short-circuit impedance tester has become an indispensable tool in power systems and industrial fields due to its ability to accurately measure the state of transformer windings. Plays an important role in multiple aspects.
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.
