HM5008 Transformer on load tap changer tester

The instrument has the functions of analyzing, storing and printing the measured data. The method of measuring the load tap changer of power transformer is backward, and there is no special test means.

It is important to diagnose the potential faults of on load tap changer in the preventive test of power equipment and the overhaul of transformer, which is of great significance to improve the reliability of power system operation.

Summary

On load tap changer tester is a comprehensive measuring instrument for measuring and analyzing the electrical performance indexes of power transformers and on load tap changers of power transformers. It adopts computer control, and through special designed measuring circuit, the transition time, transition waveform, transition resistance, three-phase synchronism and other parameters of the on load tap changer can be realized. The user can directly measure by the tap switch lead wire according to the requirement and the field condition, and also can be measured by the transformer, the three-phase bushing and the neutral point direct connection.

Advantage

1.Ray oscilloscope function

The instrument is divided into three channels and can record A, B and C phases simultaneously. The instrument can automatically capture and display the transition resistance and time jump process during the transition process. Weather free, the function is superior to the light oscillograph.

2.Strong comprehensive ability

The measurement of various parameters of on load tap changer can be realized in an instrument. If the switch is selected and switched, is there any breakpoint, transition waveform, transition time, transition resistance, three-phase synchronism and so on in the whole process. With each function button, it can analyze the time and resistance of each time in the waveform.

3.Print output. The instrument equipped with a front panel for high-speed printer paper.

4.Good anti-interference performance.

All aluminum alloy case and instrument are equipped with power supply, noise filter and anti-interference circuit, which can be reliably measured in the field of poor power quality and strong magnetic field interference.

5.Data hold, data communication.

Data and waveform measured by the user can be stored in the instrument. The stored waveform as many as 128 groups will not be lost due to power failure, the results of on-site storage can be transmitted to the computer by serial port through a dedicated data line. (special software freely supplied.).
