XW-805 Transformer On Load Tap Changer Tester
About the product
The on-load tap changer is the only moving part connected to the transformer circuit, so the detection of the on-load tap changer attracts more and more attention. In the Regulation of Power Equipment Handover and Preventive Test, it is required to check the action sequence of the on-load tap changer and measure the switching time. The instrument is mainly used to measure the transient waveform, transient time, transient resistance value at each moment, three-phase synchronization, and so on of the transformer on-load tap changer.
The instrument has a high degree of intelligence, all-Chinese menu prompts, and simple operation. The instrument has the advantages of small volume, light weight, and strong anti-interference ability, which greatly reduces 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.
