A transformer turn ratio (TTR) tester is used to measure the ratio of the number of turns in the primary winding to the number of turns in the secondary winding of a transformer. It helps detect faults in the transformer, such as shorted or open windings, and ensures the transformer is operating correctly.
Cable Hipot testing is a high-voltage test that verifies the insulation integrity of a cable. It helps detect manufacturing defects, installation damage, or degradation, ensuring reliability and preventing unexpected breakdowns in your power systems
Selecting the right battery testing equipment and suppliers is vital. It ensures accurate assessments, reliable battery performance, and supports the longevity of your critical power systems. KV Hipot is committed to providing top-quality solutions.
The temperature rise test measures how hot a transformer gets under full load conditions. It verifies that the transformer’s cooling system works correctly and that temperatures stay within safe design limits, preventing damage and ensuring reliable operation.
Dielectric tests are vital for transformer reliability. Tests like Separate Source, Induced Voltage, and Partial Discharge measurement verify insulation strength, ensuring safe operation and preventing costly failures.
Are you unsure about your transformer oil’s health? Worried about
VLF testing uses very low frequency AC voltage and is the preferred, safer method for testing modern cables like XLPE. DC Hipot testing uses direct current and can damage these cables.
Tired of batteries underperforming or failing unexpectedly? This costs you
10kV dielectric loss testing and oil dielectric loss testing are critical insulation assessments in power systems. The 10kV dielectric loss test provides a comprehensive evaluation of the transformer’s insulation system, considering the performance of the entire insulation structure, including winding insulation, core insulation, and insulating oils under actual operating voltage.
This article provides a comprehensive analysis and study of fault diagnosis and treatment of power transformers. Through a detailed discussion of fault types and causes, we identify major fault types such as overheating faults in conducting circuits, degradation of insulation levels, gas-producing faults, regulator switch faults, transformer winding deformation, transformer oil seepage defects, and capacitor bushing faults, and analyze their impact on the safe operation of the transformer
