The on-load tap switch is the only moving part connected with the transformer circuit. Therefore, more and more attention has been paid to the detection of on-load tap switch. In the electrical equipment handover and preventive test regulations, it is required to check the action sequence of on-load tap changer, measure switching time, etc.The instrument is mainly used for measuring the transition waveform, transition time, transient resistance and three-phase synchronism of transformer on-load tap changer.

Feature/Function

1. Large output current and light weight.

2.Two current output, wider test range, higher stability.

3.The transition resistance value and transition time value can be calculated automatically.

4.With perfect protection circuit, high reliability.

5.With U disk storage function, can store more data waveform.
