The Transformer On-Load Tap Changer Tester is a comprehensive testing device used to measure and analyze the electrical performance indicators of on-load tap changers in power transformers and special transformers within the power system. This instrument, through a specially designed measurement circuit, can measure parameters such as transition time, transition waveform, transition resistance, and three-phase synchronization of the on-load tap changer. Users can measure directly from the tap changer leads or by direct wiring from the transformer's three-phase bushings and neutral point, depending on their needs and site conditions.
This instrument has functions such as analyzing, storing, and printing the measured data. It solves the problem of outdated measurement methods and the lack of dedicated testing means for on-load tap changers in power transformers. It can promptly diagnose potential faults in on-load tap changers during preventive tests of power equipment and transformer overhauls, which is of great significance for improving the reliability of power system operation.
This instrument features high intelligence, with all operations guided by Chinese menu prompts, making it simple to operate. It is compact, lightweight, and has strong anti-interference capability, greatly reducing the labor intensity of field workers. It is an ideal instrument for power generation and supply units, as well as transformer manufacturing industries, to ensure safe production and improve product quality.
