TPFKC-B 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 in power systems. Through a specially designed measuring circuit, this instrument can measure parameters such as transition time, transition waveform, transition resistance, and three-phase synchronization of on-load tap changers. Users can measure directly from the tap changer leads or connect directly from the transformer three-phase bushings and neutral point according to needs and site conditions.
This instrument has functions such as analyzing, storing, and printing the measured data. It solves the problems of outdated measurement methods and lack of dedicated testing means for on-load tap changers in current power transformers. It can promptly diagnose potential faults of 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 a high degree of intelligence, with all operations guided by Chinese menu prompts, making it simple to operate. The instrument 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 and transformer manufacturing industries to ensure safe production and improve product quality.
