In a railway power supply section, routine testing is conducted on three 55kV autotransformers across two traction substations. The objective of this routine testing is to ensure the reliable operation of the substation equipment. By performing regular tests and analysis, the operational status of critical equipment can be assessed, ensuring the reliability and safety of power supply. This testing includes DC resistance test, transformer ratio test, insulation resistance test, and dielectric loss test.
During DC resistance tests on different voltage-side windings, wiring needs to be changed repeatedly, requiring workers to climb the equipment, which is time-consuming and carries high safety risks.
The strong electric field interference in the substation disturbs dielectric loss testing, leading to inaccurate data.
By using the Intelligent Anti-interference Dielectric Loss Tester, Insulation Resistance Tester, DC Resistance Tester, and Transformer Ratio Tester, this solution provides a comprehensive and efficient testing process. The equipment’s ability to handle interference ensures more accurate data, while the simplified process eliminates the need for repeated wiring changes, reducing time and improving safety.
Anti-interference capabilities ensure more accurate testing results, even in high-voltage environments.
One-time wiring setup for all transformer windings, eliminating the need to climb equipment multiple times.
Conduct all necessary tests on different transformer components with a single device, saving time and effort.
Reduced need for repetitive equipment handling, minimizing safety risks.
