XHYZ1668A On-load tap-changer tester
The on-load tap-changer is the only moving part connected to the transformer circuit, so the detection of the on-load tap-changer has attracted more and more attention. In the "Power Equipment Handover and Preventive Test Regulations", it is required to check the action sequence of the on-load tap-changer, measure the switching time, etc. The instrument is mainly used to measure the transition waveform, transition time, transition resistance value of each moment, and three-phase synchronicity of transformer on-load tap-changer.
The instrument is highly intelligent, with all Chinese menu prompts and easy operation. The instrument is small in size, light in weight, and has strong anti-interference ability, which greatly reduces the labor intensity of on-site staff. It is an ideal instrument for power generation and power supply units and transformer manufacturing industries to ensure safe production and improve product quality.
The instrument has a large output current and is light in weight;
- Test YN, Y, △ transformers, and the resistance value can be displayed directly without conversion;
- It can be measured with and without windings;
- Waveform display automatically adjusts the amplitude of resistance and time value according to the sampled value
- It has a complete protection circuit and strong reliability;
- Large 7-inch LCD display, convenient for on-site operation;
- 500 sets of data can be automatically saved internally.
