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. This instrument is mainly used to measure the transition waveform, transition time, transient resistance values at each moment, and three-phase synchronicity of transformer on-load tap changer.
The instrument has a high degree of intelligence, with all 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 generation and supply units, as well as the transformer manufacturing industry to ensure safe production and improve product quality.
1.The instrument has a large output current and a light weight;
2.Test Yn, Y, and D transformers, and display the resistance value directly without conversion;
