Huazheng Electric Manufacture HZYA-3Z Transformer On-load Tap-changer Tester

The Transformer On-load Tap-changer Tester is equipped with advanced technology that allows for real-time monitoring and testing of tap-changer operations without interrupting the power supply. This means you can conduct essential maintenance checks while your system remains fully operational, minimizing downtime and enhancing productivity. With its user-friendly interface, the tester simplifies complex testing procedures, making it accessible for both seasoned professionals and those new to transformer maintenance.

The on-load tap-changer is the only moving part connected to the transformer circuit. Therefore, the detection of the on-load tap-changer is becoming more and more important. In the "power equipment transfer and preventive test procedures", asked to check the on-load tap-changer action sequence, measurement switching time. The instrument is mainly used to measure the transformer on-load tap-changer transition waveform, transition time, the instantaneous transition resistance, three-phase synchronization and so on.
