Product Overview

The on-load tap changer is a moving component connected to the transformer circuit, so the detection of the on-load tap changer is increasingly attracting attention. In the "Power Equipment Handover and Preventive Test Regulations", it is required to check the action sequence of the on-load tap changer and measure the switching time. To this end, our company has successfully developed a transformer on-load tap changer parameter testing instrument, which is mainly used to measure the transition waveform, transition time, each transition resistance value, and three-phase synchronization of the transformer on-load tap changer.

The instrument has a high degree of intelligence, full Chinese menu prompts, and simple operation. The instrument is small in size, light in weight, and has strong anti-interference ability, greatly reducing the labor intensity of on-site workers. It is an ideal instrument for power supply and power generation units, transformer manufacturing industry to ensure production safety and product quality.
