The transformer short-circuit impedance tester plays a very important role in the detection of transformers. For the measurement of low voltage short-circuit impedance of main transformers of 110KV and above, the transformer circuit impedance tester has a very powerful testing function. The instrument adopts an adjustable power output function internally. Whether it is single-phase transformer detection or three-phase transformer detection, the tester only needs to connect one line to complete all testing tasks.
Due to the fact that measuring the short-circuit impedance of transformers is a fundamental part of routine testing projects, the tester can preliminarily evaluate the degree of winding deformation by comparing the short-circuit impedance values before and after short-circuit current impact. According to regulations, the low-voltage short-circuit impedance of a transformer should not change by more than 2% after being subjected to short-circuit current impact. This test can not only reflect the impact of short-circuit current on transformers during actual operation, but also detect mechanical damage that may occur during transportation and installation. Therefore, the low voltage short-circuit impedance test is considered a key basis for determining whether the transformer can be used normally and whether further disassembly inspection is needed.
Through the above introduction, we can know that the transformer short-circuit impedance tester, as an efficient and practical device, can accurately evaluate the damage of transformers and provide strong support for maintenance and repair of transformers. This is the importance of using a transformer short-circuit impedance tester. This tester plays a decisive role in determining whether the transformer has faults and whether it needs major repairs.
