Product Introduction

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.
The instrument is highly intelligent, all English menu prompts, simple operation. Instrument small size, light weight, anti-interference ability, greatly reducing the labor intensity of the site staff, is the power supply units, transformer manufacturing industry to ensure safe production, improve product quality ideal instrument.
