Complaint
The on load tap changer is the only moving component connected to the transformer circuit, so the detection of on load tap changer is receiving increasing attention. In the "Regulations for Handover and Preventive Testing of Electric Power Equipment", it is required to check the action sequence of on load tap changer, measure the switching time, etc. For this reason, our company has successfully developed this testing instrument, which is mainly used to measure the transition waveform, transition time, transient resistance values at each moment, and three-phase synchronization of transformer on-load tap changer.
The instrument has a high degree of intelligence, with all Chinese menu prompts and simple operation. The instrument has small size, light weight, and strong anti-interference ability, greatly reducing the labor intensity of on-site workers. It is an ideal instrument for power generation and supply units, as well as the transformer manufacturing industry to ensure safe production and improve product quality.| Technical indicators | |
