Transformer on load tap changer tester DYYC-M Touch screen

1、 Product Overview

On load tap changer is the only moving part connected with the transformer circuit, so the detection of on load tap changer has attracted more and more attention. In the Code for Handover and Preventive Test of Electric Equipment, it is required to check the action sequence of on load tap changer and measure the switching time. The instrument is mainly used to measure the transition waveform, transition time, transient resistance value and three-phase synchronization of transformer on load tap changer.

2、 Functional features

 The instrument has large output current and light weight;

 Two gear current output, wider test range and higher stability;

 It can automatically calculate the transition resistance value and transition time value;

 Complete protection circuit with strong reliability;

 8-inch large LCD display, convenient for on-site operation;

 With U disk storage function, more data can be stored.

 The keyboard is operated independently, making the operability of the instrument faster and more convenient.
