Profile:
The KDKC-2020 transformer on load tap changer tester is a comprehensive measuring instrument used to measure and analyze the electrical performance indicators of power transformers and special transformer on load tap changers in power systems. It adopts computer control and can measure the transition time, transition waveform, transition resistance, three-phase synchronicity, and other parameters of the on load tap changer through a specially designed measurement circuit. Users can directly measure them through the tap changer leads according to their needs and site conditions, or directly connect them through the transformer three-phase bushing and neutral point for measurement.
The KDKC-2020 transformer on load tap changer tester has functions such as displaying, analyzing, storing, and printing the measured data. Solved the problem of outdated measurement methods and lack of dedicated testing methods for on load tap changers in power transformers. Timely diagnosis of potential faults in on load tap changers during preventive testing of power equipment and transformer overhaul is of great significance for improving the reliability of power system operation.
Features:
1. Test Y0, Y, and △ transformers, and display the resistance values directly without conversion.
2. Humanized data analysis can automatically identify faults in the middle of the waveform and mark them.
3. The waveform display automatically adjusts the amplitude of resistance and time based on the sampled data.
4. It can be tested with or without windings.
5. The four terminal wiring method provides high-precision resistance measurement without the need for wire compensation.
6. Continuous testing can be conducted during the testing process to save time on transformer power outages.
7. This transformer on load switch tester can generate Word reports for easy data management and querying.
8. The instrument is controlled by a small computer and equipped with an external 800 × 480 color LCD touch screen.
9. High speed printer, supports external mouse, easy to operate.
10. The instrument can automatically save 1000 sets of data internally, or it can be saved externally with a USB flash drive.
