BYKC-2000 modelTransformer on load switch testerThe new testing principle utilizes microcomputer technology to test the performance of various on load tap changers of power transformers on the production site without disassembling and lifting switches, displaying and printing excessive waveforms and parameters. And according to the needs and on-site conditions, the measurement can be directly carried out by the tap changer lead, or by directly connecting the transformer three-phase bushing and neutral point for measurement.
Transformer on load switch testerIt is a comprehensive measuring instrument used to measure and analyze the electrical performance indicators of on load tap changers for power transformers and special transformers in power systems. It is controlled by a computer and can measure parameters such as transition time, transition waveform, transition resistance, and three-phase synchronicity of the on load tap changer through a specially designed measurement circuit. Users can directly measure these parameters through the tap changer leads according to their needs and site conditions, or directly connect the transformer three-phase bushing and neutral point for measurement.
This instrument has functions such as analyzing, storing, and printing the measured data. The problem of outdated measurement methods and lack of testing methods for on load tap changers in power transformers has been solved. Potential faults of on load tap changers can be diagnosed in a timely manner during preventive testing of power equipment and transformer maintenance, which is of great significance for improving the reliability of power system operation
