LB transformer on load tap changer testerIntroduction:
The transformer on load switch tester is a comprehensive measuring instrument used by Wuhan Guoyi Technology to measure and analyze the electrical performance indicators of power transformers and special transformer on load tap changers in power systems based on the principles of the "Power Equipment Handover and Preventive Testing Regulations" and relevant regulations. It adopts computer control and can measure parameters such as transition time, transition waveform, transition resistance, three-phase synchronicity, etc. of on load tap changers through specially designed measurement circuits. The 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.
