Product Introduction
The on-load tap changer is the only moving part connected with the transformer circuit so more and more attention has been paid to the detection of the on-load tap changer.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.This device is mainly used for measuring the transition waveform transition time transient resistance of transformer on-load tap changer three-phase synchronism etc.
product names:On - load tap - changer tester transformer on - load tap - changer tester transformer on - load switch tester
Product Characteristics
1,Instrument output current light weight
2,Two current output wider test range higher stability
3,It can calculate the transition resistance value and transition time value automatically
4,Has the perfect protection circuit the reliability is strong
5,5.7 "large LCD display easy to operate on site
6,With usb flash disk storage function you can store more data waveform
7,The keyboard and the one-key flying shuttle operate independently making the instrument operate more quickly and conveniently
