Product Introduction

The on-load tap-changer tester is designed according to the high-voltage test equipment of the power industry standard of the People's Republic of China. The general technical conditions DL/T846 and 8-2004 can meet the requirements of the "Handover and Preventive Test Rules for Electric Power Equipment", such as checking the action sequence of on-load tap-changer and measuring the switching time. It can measure the transition time, transition waveform, transition resistance and three-phase synchronization of on-load tap-changer accurately. It is an ideal equipment for testing on-load tap-changer. (Users are on-load switches with capacitance regulation, please inform in advance)

Product features

Testing Y0 Y Delta transformer, resistance value does not need to be converted to display directly;

Data analysis is humanized, which can automatically find the fault in the middle of the waveform and mark it.

The display of waveform is to automatically adjust the magnitude of resistance and time according to the sampled data.

Delta transformer can display three-phase synchronization.

It can be tested with or without windings.

Four-terminal connection provides high precision resistance measurement without wire compensation.

In the middle of the test, continuous test can be carried out to save the time of transformer outage.

The instrument can survive word report and facilitate data management and query.

The instrument is controlled by a small computer. It is equipped with 800 *480 color LCD touch screen and high-speed printer. It supports hanging mouse and is easy to operate.

The instrument can automatically save 1000 sets of data, or can be stored on an external U disk.
