Product Introduction

Its main business is the production, manufacture and sales of electrical equipment and testing instruments.

I.Description

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 Chinese 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.

II.Features

Large output current, light weight

Test YO, Y, △ type transformer, the resistance unnecessary to be converted but directly display

With winding or without winding measurement

Waveform display automatically adjusts the resistance according to the sampled value, the time value amplitude

With perfect protection circuit, reliability and strong

7-inch large LCD display, easy on-site operation
