Digital Portable Transformer on-Load Tap-Changer Tester Fast and Accurate

XZH TEST Digital Portable Transformer on-Load Tap-Changer Tester Fast and Accurate

The on-load tap-changer is the only moving part that is connected to the transformer circuit, so the detection of the on-load tap-changer is getting more and more attention. In the "Procedures for Handling and Preventive Tests for Electrical Equipment", it is required to check the sequence of actions and the switching time of the on-load tap-changer.
The XHYZ1668A transformer on-load tap-changer tester is mainly used to measure the transition waveform, transition time, transient resistance value, and three-phase synchronization of the on-load tap-changer.

1. The instrument has large output current and its weight is light;
2. Two-stage current output, wider test range and higher stability;
3. Can automatically calculate the transition resistance value and transition time;
4. It has perfect protection circuit and strong reliability;
5. 5.7-inch large LCD display, it's easy for on-site operation;
6. U disk storage function, can store more waveforms data .
7. The keyboard and one-button shuttle are operated independently, which makes the instrument more convenient to operate.
