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 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.

: on - load tap - changer tester transformer on - load tap - changer tester transformer on - load switch tester

• 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
