XHYZ1668 On-load switch tester
Product description
The on-load tap-changer is the only moving part connected to the transformer circuit. Therefore, the detection of on-load tap-changers has attracted more and more attention. This instrument is mainly used to measure the transition waveform, transition time, transient resistance value of the on-load tap changer of transformer, and three-phase consistency.
The instrument is highly intelligent, with all English menu prompts and simple operation. The instrument is small in size, light in weight, and strong in anti-interference ability, which greatly reduces the labor intensity of on-site workers. 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 main functions and Features
- 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.
