The on-load tap changer is the only moving part connected to the transformer circuit, so the detection of on-load tap changers has attracted more and more attention. In the "Electric Power Equipment Handover and Preventive Test Regulations", it is required to check the action sequence of the on-load tap changer and measure the switching time. This instrument is mainly used to measure the transition waveform, transition time, each instantaneous transition resistance value, three-phase synchronization, etc. of the on-load tap changer of the transformer
1. The instrument has large output current and light weight;
2. Test Yn, Y, and D type transformers, and the resistance value is directly displayed without conversion;
3. It can be measured with or without windings;
4. The waveform display automatically adjusts the resistance and time value amplitude according to the sampling value
5. It has a complete protection circuit and strong reliability;
6. Seven-inch high-brightness touch color LCD, clear display under strong light, full touch screen operation, free switching between Chinese and English
7. Built-in large-capacity lithium battery, no external power supply (optional);
8. 500 sets of data can be automatically saved internally.
9. The instrument can be used with Android phones or tablets, follow the WeChat public account, download the dedicated APP, control the instrument throughout the process through dedicated software, and upload the test data for easy reference.
